Int J Biol Macromol 2022; 194:452-460.

Abstract
Halochromic agent is easy to fall off from the surface of colorimetric membranes during fish freshness monitoring, which would decay the test accuracy. In order to increase its anchoring, citrated methacrylated urethane (CMU) synthesized by using tributyl citrate, β-hydroxyethyl methacrylate and diphenyl-methane-diisocyanate as a halochromic agent was grafted on polylactic acid (PLA). The CMU grafted PLA (PLA-CMU) together with tetrabutylammonium chloride (TBAC) prepared colorimetric membranes via electrospinning. 1H NMR and FTIR analysis showed successful bonding between CMU and PLA, and PLA-CMU grafting efficiency reached to the maximum value of 11.15%. Moreover, DSC confirmed that PLA-CMU existed low cold-crystallization temperature due to the excellent compatibility of CMU with PLA, which enhanced the anchoring of CMU effectively. Nanofiber-based PLA-CMU/TBAC colorimetric membrane enhanced the probability of molecules being captured due to its porous structure and large specific surface area. In addition, the increase in hydrophilicity of the membrane can provide a microenvironment for liquid phase reaction, exhibiting obvious color-changing sensitivity during cod freshness monitoring, from white color to light orange or pink with the deterioration of cod at 25 °C and 4 °C respectively. The results demonstrate PLA-CMU/TBAC colorimetric membranes would provide a simple and promising strategy for monitoring fish freshness.

Abstract
A wide variety of quaternary ammonium compounds (QACs) have escalated the attraction of researchers to explore the application of QACs. The compounds have frequently been synthesized through alkylation or quaternization of tertiary amines with alkyl halides. Recently, QACs have been applied to compatibilize polymer blends and polymer composites in improving their thermo-mechanical properties. This concise review concentrates on the application of two types of QACs as compatibilizers for polymer blends and polymer composites. The types of QACs that were effectively applied in the blends and composites are quaternary ammonium surfactants (QASs) and quaternary ammonium ionic liquids (QAILs). They have been chosen for the discussion because of their unique chemical structure which can interact with the polymer blend and composite components. The influence of QASs and QAILs on the thermo-mechanical properties of the polymer blends and polymer composites is also described. This review could be helpful for the polymer blend and polymer composite researchers and induce more novel ideas in this research area.

Abstract
An enhancement of environmental concern lately has improved the awareness of researchers in employing eco-friendly solvents for processing biopolymers. Recently, ionic liquids have been utilized to prepare biopolymer blends as they are non-volatile and recyclable. Biopolymers such as cellulose, chitin, chitosan, keratin, lignin, silk, starch, and zein are widely used for the preparation of biopolymer blends via dissolution in ionic liquids, followed by coagulation procedure. In this concise review, three types of ionic liquids based on imidazolium cations combined with different counter anions that are frequently utilized to prepare biopolymer blends are described. Moreover, three types of biopolymer blends that are prepared in ionic liquids were classified, specifically polysaccharide/polysaccharide blends, polysaccharide/polypeptide blends, and polysaccharide/bioplastic blends. The physicochemical properties of biopolymer blends prepared in different imidazolium-based ionic liquids are also concisely reviewed. This paper may assist the researchers in the polymer blend area and generate fresh ideas for future research.

Abstract
Studies of phase separation in lower critical solution temperature (LCST) polymer blends exposed to high-pressure CO2 provide an insight to their physical properties. Through using in situ high-pressure ATR-FTIR spectroscopic imaging, this work visualized the dynamic process of phase separation in Polycaprolactone (PCL)/Poly (lactic acid) (PLA) blend under high-pressure CO2 for the first time. ATR-FTIR spectroscopic images revealed that phase separation in PCL/PLA blends occurs with increasing temperature or upon exposure to high-pressure CO2. The change in the morphology of PCL-rich and PLA-rich domains in the ATR-FTIR spectroscopic images can be used to compare the extent of phase separation under different conditions. It is found that the extent of phase separation in PCL/PLA blends under high-pressure CO2 is enhanced with increasing temperature, CO2 pressure and exposure time. The effect of different molecular weights of one blend component, PCL, on the phase separation in PCL/PLA blends was also studied. This pioneering methodology opens possibilities to visualize the process of phase separation in LCST polymer blend systems and it can also be applied to study the process of interdiffusion in upper critical solution temperature (UCST) polymer blends.

Abstract
Polymeric hydrogels from bacterial cellulose (BC) have been widely used for the development of wound dressings due to its water holding capacity, its high tensile strength and flexibility, its permeability to gases and liquids, but lacks antibacterial activity. In this work, we have developed novel antimicrobial hydrogels composed of BC and the antimicrobial poly(3-hydroxy-acetylthioalkanoate-co-3-hydroxyalkanoate) (PHACOS). Hydrogels based on different PHACOS contents (20 and 50 wt%) were generated and analysed through different techniques (IR, DSC, TGA, rheology, SEM and EDX) and their bactericidal activity was studied against Staphylococcus aureus. PHACOS20 (BC 80%-PHACOS 20%) hydrogel shows mechanical and thermal properties in the range of human skin and anti-staphylococcal activity (kills 1.8 logs) demonstrating a huge potential for wound healing applications. Furthermore, the cytotoxicity assay using fibroblast cells showed that it keeps cell viability over 85% in all the cases after seven days.

Abstract
Poly(3-hydroxybutyrate-co-3-valerate), PHBV, is a bacterial thermoplastic biopolyester that possesses interesting thermal and mechanical properties. As it is fully biodegradable, it could be an alternative to the use of commodities in single-use applications or in those intended for composting at their end of life. Two big drawbacks of PHBV are its low impact toughness and its high cost, which limit its potential applications. In this work, we proposed the use of a PHBV-based compound with purified α-cellulose fibres and a thermoplastic polyurethane (TPU), with the purpose of improving the performance of PHBV in terms of balanced heat resistance, stiffness, and toughness. Three reactive agents with different functionalities have been tested in these compounds: hexametylene diisocianate (HMDI), a commercial multi-epoxy-functionalized styrene-co-glycidyl methacrylate oligomer (Joncryl® ADR-4368), and triglycidyl isocyanurate (TGIC). The results indicate that the reactive agents play a main role of compatibilizers among the phases of the PHBV/TPU/cellulose compounds. HMDI showed the highest ability to compatibilize the cellulose and the PHBV in the compounds, with the topmost values of deformation at break, static toughness, and impact strength. Joncryl® and TGIC, on the other hand, seemed to enhance the compatibility between the fibres and the polymer matrix as well as the TPU within the PHBV.

Abstract
In the present study, we propose a green route to prepare poly(3-hydroxybutyrate) [(P(3HB)] grafted ethyl cellulose (EC) based green composites with novel characteristics through laccase-assisted grafting. P(3HB) was used as a side chain whereas, EC as a backbone material under ambient processing conditions. A novel laccase obtained from Aspergillus niger through its heterologous expression in Saccharomyces cerevisiae was used as a green catalyst for grafting purposes without the use of additional initiator and/or cross-linking agents. Subsequently, the resulting P(3HB)-g-EC composites were characterized using a range of analytical and imagining techniques. Fourier transform infrared spectroscopy (FT-IR) spectra showed an increase in the hydrogen-bonding type interactions between the side chains of P(3HB) and backbone material of EC. Evidently, X-ray diffraction (XRD) analysis revealed a decrease in the crystallinity of the P(3HB)-g-EC composites as compared to the pristine individual polymers. A homogeneous P(3HB) distribution was also achieved in case of the graft composite prepared in the presence of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) as a mediator along with laccase as compared to the composite prepared using pure laccase alone. A substantial improvement in the thermal and mechanical characteristics was observed for grafted composites up to the different extent as compared to the pristine counterparts. The hydrophobic/hydrophilic properties of the grafted composites were better than those of the pristine counterparts.

Abstract
Although multivariate curve resolution (MCR) has been applied to the analysis of Fourier transform infrared (FTIR) imaging, it is still problematic to determine the number of components. The reported methods at present tend to cause the components of low concentration missed. In this paper a new idea was proposed to resolve this problem. First, MCR calculation was repeated by increasing the number of components sequentially, then each retrieved pure spectrum of as-resulted MCR component was directly compared with a real-world pixel spectrum of the local high concentration in the corresponding MCR map. One component was affirmed only if the characteristic bands of the MCR component had been included in its pixel spectrum. This idea was applied to attenuated total reflection (ATR)/FTIR mapping for identifying the trace additives in blind polymer materials and satisfactory results were acquired. The successful demonstration of this novel approach opens up new possibilities for analyzing additives in polymer materials.

Abstract
Bacterial cellulose (BC) exhibits high purity, mechanical strength and an ultra-fine fibrous 3-D network structure with bio-compatible and bio-degradable characteristics, while P(3 HB) are a bio-degradable matrix material derived from natural resources. Herein, we report a mild and eco-friendly fabrication of indigenously isolated P(3 HB) based novel composites consisting of BC (a straight-chain polysaccharide) as a backbone polymer and laccase was used as a grafting tool. The resulting composites were characterised by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), dynamic mechanical analyser (DMA) and water contact angle analyser (WCA). The FTIR spectra of the pure P(3 HB) and P(3 HB) containing graft composites [P(3 HB)-g-BC] showed their strong characteristic bands at 3358 cm(-1), 1721 cm(-1) and 1651 cm(-1), respectively. A homogenous dispersion of P(3 HB) in the backbone polymer of BC was achieved as evident by the SEM micrographs. XRD pattern for P(3 HB) showed distinct peaks at 2θ values that represent the crystalline nature of P(3 HB). While, in comparison with those of neat P(3 HB), the degree of crystallinity for P(3 HB)-g-BC decreased and this reduction is mainly because of the new cross-linking of P(3 HB) within the backbone polymer that changes the morphology and destroys the crystallites. Laccase-assisted graft composite prepared from P(3 HB) and BC was fairly flexible and strong, judged by the tensile strength (64.5 MPa), elongations at break (15.7%), and Young's modulus (0.98 GPa) because inherently high strength of BC allowed the mechanical properties of P(3 HB) to improve in the P(3 HB)-g-BC composite. The hydrophilic property of the P(3 HB)-g-BC was much better than that of the individual counterparts which is also a desired characteristic to enhance the biocompatibility of the materials for proper cell adhesion and proliferation.

Abstract
Biomimic silk fibers with refined crystalline structure were produced via incorporating cellulose nanocrystals into silk fibroin matrix to mimic the β-sheet crystallites in natural silk. The fibers exhibit excellent thermal and mechanical properties, attributed to the strong hydrogen bonding interactions between cellulose nanocrystals and silk fibroin as well as cellulose nanocrystal-induced ordered structure.

Abstract
More and more attention has been paid to environmentally friendly bio-based renewable materials as the substitution of fossil-based materials, due to the increasing environmental concerns. In this study, regenerated cellulose films with enhanced mechanical property were prepared via incorporating different plasticizers using ionic liquid 1-allyl-3-methylimidazolium chloride (AmimCl) as the solvent. The characteristics of the cellulose films were investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM), thermal analysis (TG), X-ray diffraction (XRD), 13C Solid-state cross-polarization/magic angle spinning nuclear magnetic resonance (CP/MAS NMR) and tensile testing. The results showed that the cellulose films exhibited a homogeneous and smooth surface structure. It was noted that the thermal stability of the regenerated cellulose film plasticized with glycerol was increased compared with other regenerated cellulose films. Furthermore, the incorporation of plasticizers dramatically strengthened the tensile strength and improved the hydrophobicity of cellulose films, as compared to the control sample. Therefore, these notable results exhibited the potential utilization in producing environmentally friendly cellulose films with high performance properties.

Abstract
Ionic liquid solvent, 1-butyl-3-methylimidazolium chloride (BMIM[Cl]) was used to prepare cellulose/polycaprolactone (PCL) blend films. This solvent was recycled with high yield and purity after blend precipitation. The inter- and intra-molecular hydrogen bonding interactions in these blends were investigated by Fourier transform infrared (FTIR) spectroscopy and it was found that a new peak in the carbonyl region, assigned to hydrogen bonding between carbonyl groups of PCL and hydroxyl groups of cellulose in blends with PCL composition less than 40 wt%. Differential scanning calorimetry (DSC) results implied a partial miscibility of the two components by melting point depression. Moreover, the tensile properties of the blends can be adjusted by incorporating various amounts of PCL into cellulose. The blends show significant enhancement of thermal stability compared to the regenerated cellulose when the content of PCL is higher than 40 wt%. This work demonstrates an effective approach for the processing biodegradable blends from natural and synthetic polymers.
