Hajieghrary F, Ghanbarzadeh B, Pezeshki A, Dadashi S, Falcone PM. Development of Hybrid Electrospun Nanofibers: Improving Effects of Cellulose Nanofibers (CNFs) on Electrospinnability of Gelatin. Foods 2024; 13:2114. [PMID: 38998620 DOI: 10.3390/foods13132114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2024] [Revised: 06/24/2024] [Accepted: 06/28/2024] [Indexed: 07/14/2024] Open
Abstract
Cellulose nanofibers (CNFs) were used to improve the electrospinnability of the gelatin protein in a water/ethanol/acetic acid (3:2:3, v/v) solution. The effects of different concentrations of CNFs (0.5-4%) on the important physical properties of the gelatin solution (15%), including rheology, conductivity, and surface tension, were investigated. The apparent viscosity and shear-thinning behavior were increased by increasing the CNF concentration from 0 to 4% at a low shear rate (<10 s-1). CNFs also increased the electrical conductivity and surface tension of the gelatin solution. Scanning electron microscopy (SEM) images revealed uniformly ordered structures with good continuity without fracture or bead formation in all hybrid nanofibers. They also showed that the average diameters of fibers decreased from 216 nm in the pure gelatin nanofibers to 175.39 nm in the hybrid gelatin/CNF (4%) ones. Differential scanning calorimetry (DSC) results showed that CNFs increased Tg, and X-ray diffraction (XRD) analysis showed that the electrospinning process caused the formation of more amorphous structures in the gelatin/CNF hybrid nanofibers. The tensile test indicated that by adding 2% CNFs, the ultimate tensile strength (UTS) and strain at break (SB) of nanofiber mats increased from 4.26 to 10.5 MPa and 3.3% to 6.25%, respectively. The current study indicated that incorporating CNFs at the optimal concentration into a gelatin solution can improve the resulting hybrid nanofibers' morphology, average diameter, and mechanical properties.

Abstract
Lithium-ion batteries, as an excellent energy storage solution, require continuous innovation in component design to enhance safety and performance. In this review, we delve into the field of eco-friendly lithium-ion battery separators, focusing on the potential of cellulose-based materials as sustainable alternatives to traditional polyolefin separators. Our analysis shows that cellulose materials, with their inherent degradability and renewability, can provide exceptional thermal stability, electrolyte absorption capability, and economic feasibility. We systematically classify and analyze the latest advancements in cellulose-based battery separators, highlighting the critical role of their superior hydrophilicity and mechanical strength in improving ion transport efficiency and reducing internal short circuits. The novelty of this review lies in the comprehensive evaluation of synthesis methods and cost-effectiveness of cellulose-based separators, addressing significant knowledge gaps in the existing literature. We explore production processes and their scalability in detail, and propose innovative modification strategies such as chemical functionalization and nanocomposite integration to significantly enhance separator performance metrics. Our forward-looking discussion predicts the development trajectory of cellulose-based separators, identifying key areas for future research to overcome current challenges and accelerate the commercialization of these green technologies. Looking ahead, cellulose-based separators not only have the potential to meet but also to exceed the benchmarks set by traditional materials, providing compelling solutions for the next generation of lithium-ion batteries.

Int J Biol Macromol 2023:125482. [PMID: 37348576 DOI: 10.1016/j.ijbiomac.2023.125482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/09/2023] [Accepted: 06/17/2023] [Indexed: 06/24/2023]
Abstract
In this study, carbon dots (CDs), cellulose nanofibers (CNF) and essential oil nanoemulsion (EON) were extracted from the aril waste of Torreya grandis following nuts production. These three nanomaterials were formulated for the preparation of a composite film to be employed for postharvest tomato storage. Visual, microscopical and physicochemical properties of the prepared nanocomposite films were analyzed at different levels of CDs and CNF for optimization purposes. The UV absorption and antioxidant capacity of gelatin film with 10 % CDs (G/10CD) were enhanced compared with gelatin (G) film, concurrent with a reduction in water barrier capacity, water contact angle (WCA) and tensile strength (TS). Compared with G/10CD film, the WCA of gelatin film after incorporation of 10 % CDs and 3 % CNF (G/10CD/3CNF) was significantly increased by 14.5°at 55 s. In contrast, TS increased by 1.26 MPa, as well as the significant enhancement in water barrier capacity. The above composite film mixed with NEO (G/10CD/3CNF/EON) exerted further antimicrobial effects against Escherichia coli. G/10CD/3CNF/EON coating effectively extended tomato shift life compared with the control group. Therefore, this new eco-friendly film presents several advantages of biodegradability, sustainability as well as multifunctional properties posing it as potential packaging material for food applications.

Mechanical properties of cellulose nanofibril papers and their bionanocomposites: A review. Carbohydr Polym 2021; 273:118507. [PMID: 34560938 DOI: 10.1016/j.carbpol.2021.118507] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 07/14/2021] [Accepted: 07/26/2021] [Indexed: 12/25/2022]
Abstract
Cellulose nanofibril (CNF) paper has various applications due to its unique advantages. Herein, we present the intrinsic mechanical properties of CNF papers, along with the preparation and properties of nanoparticle-reinforced CNF composite papers. The literature on CNF papers reveals a strong correlation between the intrafibrillar network structure and the resulting mechanical properties. This correlation is found to hold for all primary factors affecting mechanical properties, indicating that the performance of CNF materials depends directly on and can be tailored by controlling the intrafibrillar network of the system. The parameters that influence the mechanical properties of CNF papers were critically reviewed. Moreover, the effect on the mechanical properties by adding nanofillers to CNF papers to produce multifunctional composite products was discussed. We concluded this article with future perspectives and possible developments in CNFs and their bionanocomposite papers.

Abstract
A highly transparent cellulose film with a high built-in haze is emerging as a green photonic material for optoelectronics. Unfortunately, attaining its theoretical haze still remains a challenge. Here, we demonstrate an all-cellulose composite film with a 90.1% transmittance and a maximal transmission haze of 95.2% close to the theoretical limit (∼100%), in which the entangled network of softwood cellulose fibers works as strong light scattering sources and regenerated cellulose (RC) with undissolved fibril bundles functions as a matrix to simultaneously improve the optical transparency and transmission haze. The underlying mechanism for the ultrahigh haze is attributed to microsized irregularities in the refractive index, arising primarily from the crystalline structure of softwood fibers, undissolved nanofibril bundles in RC, and a small number of internal cavities. Moreover, the resulting composite film presents a folding resistance of over 3500 times and good water resistance, and its application in a perovskite solar cell as an advanced light management layer is demonstrated. This work sheds light on the design of a highly transparent cellulose film with a haze approaching the theoretical limit for optoelectronics and brings us a step further toward its industrial production.

Abstract
Ecofriendly materials based on well-preserved and nanostructured wood cellulose fibers are investigated for the purpose of load-bearing applications, where optical transmittance may be advantageous. Wood fibers are subjected to mild delignification, flow orientation, and hot-pressing to form an oriented material of low porosity. The biopolymer composition of the fibers is determined. Their morphology is studied by scanning electron microscopy, cellulose orientation is quantified by X-ray diffraction, and the effect of beating is investigated. Hot-pressed networks are impregnated by a methyl methacrylate monomer and polymerized to form thermoplastic wood fiber/poly(methyl methacrylate) biocomposites. Tensile tests are performed, as well as optical transmittance measurements. Structure-property relationships are discussed. High-density molded fibers from holocellulose have mechanical properties comparable with nanocellulose materials and are recyclable. The thermoplastic matrix biocomposites showed superior mechanical properties (Young's modulus of 20 GPa and ultimate strength of 310 MPa) at a fiber volume fraction of 52%, with high optical transmittance of 90%. The study presents a scalable approach for strong, stiff, and transparent molded fibers/biocomposites.

Abstract
Electrically conductive cellulose nanopapers (EC-CNPaps) were fabricated by the droplet-coating of multiwall carbon nanotubes (MWCNTs) on cellulose nanopapers (CNPaps), and the effects of the process factors on the electrical conductivity of EC-CNPaps were investigated. The type of CNPaps (made of softwood nanofibrillated cellulose or bacterial cellulose nanofibres), the drying methods of CNPaps (air drying, freeze drying, and oven drying), the applied method for the stabilisation and the concentration of MWCNT-water solutions, and the droplet-coating temperatures (≈23 °C and ≈60 °C) were the examined variable factors. Overall, the oven-dried nanofibrillated cellulose paper as a substrate, 0.1 wt. % of the gum Arabic stabilised MWCNT-water solution ink, and the droplet coating at 60 °C were introduced as the optimum conditions of the examined process factors in this study.

Abstract
Nano cellulose is attracting great interest in food and nutraceutical fields and also provides a potential additive to develop functional meat products such as low fat sausage. Here, we compared 1 wt% aqueous dispersion of cellulose nanofiber (CNF) and its palm oil Pickering emulsion (CPOE) at the ratio of 1:1 (water: oil, v:v) for being fat alternatives replacing 30% and 50% of the original fat of the emulsified sausage. Replacing fat by CPOE and CNF resulted in lower fat content, lower cooking loss and higher moisture content and higher lightness values (P ≤ 0.05) at both fat levels. Textural analysis indicated that the products formulated with CPOE showed higher hardness, springiness, chewiness and the texture was enhanced by the addition of CNF, especially when 30% fat was substituted. Compared with the full-fat control, the sausages formulated with CPOE became more elastic and compact, especially by the incorporation of CNF according to the rheology and scanning electron microscope results. The reformulated products with CPOE and CNF at the 30% level showed higher sensory scores (P ≤ 0.05) while at the 50% level produced comparable quality to the control, but no significant differences were found in the overall acceptability. In summary, CNF and its Pickering emulsion provide the potential as potential fat alternatives for developing low fat meat products. PRACTICAL APPLICATIONS Cellulose nanofibers present a variety of distinguishing properties, such as large surface area, great stability and high strength. The ability to stabilize emulsions and good biocompatibility enlarge its application in food. In this study, we attempted to use cellulose nanofibers and its palm oil Pickering emulsion as fat substitutes to partly replace the original fat of pork emulsified sausages, hoping to provide some basic information for using cellulose nanofibers and its Pickering emulsion as fat substitute to high fiber, low fat meat products.
