Abstract
Polypyrrole (PPy) is a promising material for the fabrication of flexible energy storage devices and much research has been published. However, no statistical tools have been used to relate PPy synthesis conditions to its energy storage performance, considering not only the main synthesis factors but also their interactions. In this work, we use a factorial design of experiments to evaluate the influence of two electropolymerization methods and three synthesis parameters on the energy storage capacity of PPy coatings. The polymers were characterized by cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), electrochemical impedance spectroscopy (EIS), Raman spectroscopy, and scanning electron microscopy (SEM). Statistical tests showed that ClO4 --doped PPy exhibits higher capacitances than p-toluenesulfonate (pTS)-doped PPy, with a maximum capacitance of 353.75 ± 1.6 F g-1 at 1 A g-1. However, the pTS-doped PPy had better cycling stability, losing only 10% of its original energy storage capability after 5000 charge-discharge cycles at 1 A g-1. The best energy densities and power densities were 49.1 ± 0.2 Wh kg-1 and 2297 ± 15 W kg-1 (ClO4 --doped PPy) and 47.8 ± 1.5 Wh kg-1 and 2191 ± 91 W kg-1 (pTS-doped PPy), respectively, which indicates that through statistical tools, the optimal synthesis conditions are refined to take advantage of the energy storage properties of this polymer.

WATER RESEARCH 2021; 207:117825. [PMID: 34763279 DOI: 10.1016/j.watres.2021.117825] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 10/09/2021] [Accepted: 10/29/2021] [Indexed: 06/13/2023]
Abstract
Still ∼10% of world's population has no sustainable access to centralized water supply system, causing millions of deaths annually by waterborne diseases. Here, we develop polypyrrole nanowire arrays (PPyNWs)-modified electrodes by polymerization of pyrrole on graphite felt for point-of-use water disinfection via low-voltage electroporation. A flow-through mode is specially applied to alleviate diffusion barrier of pyrrole in the porous graphite felt for uniform PPyNWs growth. The flow-through disinfection device using the optimized PPyNWs electrode achieves above 4-log removal for model virus (MS2) and gram-positive/negative bacteria (E. faecalis and E. coli) at applied voltage of 1.0 V and fluxes below 1000 and 2500 L/m2/h. Electroporation is recognized as the dominant disinfection mechanism by using square-wave alternating voltage of ±1.0 V to eliminate the electrochemical reactions. In-situ sampling experiments reveal that anode acts as the main disinfection function due to its electric field attraction with negatively charged E. coli cells. The live/dead baclight staining experiments indicate an adsorption-desorption process of E. coli cells on anode, and the adsorption-desorption balance determines the disinfection abilities of PPyNWs anode. Under 1.0 V and 2000 L/m2/h, the disinfection device enables above 4-log E. coli removal in tap water within 7-day operation with energy consumption below 20 mJ/L, suggesting its sound application potential for point-of-use water disinfection.

Abstract
Flexibility of the films and the limited ion transport in the vertical direction of film highly restrict the development of flexible supercapacitors. Herein, we have developed hybrid porous films consisting of N-doped holey graphene nanosheets (NHGR) with abundant in-plane nanopores and the vertically aligned polyaniline nanowires arrays on polypyrrole nanotubes (PPy@PANI) via a two-step oxidative polymerization strategy and vacuum filtration. The rational design can efficiently shorten the diffusion path of electrons/ions, alleviate volume variation of electrodes during cycling, enhance electric conductivity of the hybrids, and while offer abundant active interfacial sites for electrochemical reaction. Benefiting from the distinctive structural and compositional merits, the obtained PPy@PANI/NHGR film electrode manifests an excellent electrochemical properties in terms of specific capacity (1348 mF cm-2at a current density of 1 mA cm-2), rate capability (81.2% capacitance retention from 1 to 30 mA cm-2), and cycling stability (capacitance retention of 73.7% at 20 mA cm-2after 7000 cycles). Matched with NHGR negative electrode, the assembled flexible all-solid-state asymmetric supercapacitor displays a remarkable areal capacitance of 359 mF cm-2at 5 mA cm-2, maximum areal energy density of 112.2μWh cm-2at 3.747 mW cm-2, and good flexibility at various bending angles while preserving stable cycling performance. The result shows the PPy@PANI/NHGR film with high flexibility and 3D ions transport channels is highly attractive for flexible energy storage devices.

Abstract
Advanced thermal insulation materials with low thermal conductivity and robustness derived from regenerative resources are badly needed for building energy conservation. Among them, nanofibrillated cellulose aerogels have huge application potential in the field of thermal insulation materials, but it is still a challenge to prepare cellulose aerogels of excellent comprehensive properties in a simple way. Herein, we demonstrate a unidirectional freeze-drying strategy to develop a novel "robust-soft" anisotropic nanofibrillated cellulose aerogel (NFC-Si-T) by integrating nanofibrillated cellulose (NFC) and Si-O-Si bonding networks under the catalytic dehydration of p-toluenesulfonic acid (TsOH). The anisotropic structure endows the NFC-Si-T with high flexibility that can be easily bent or even tied with a knot, and in addition, it possesses high Young's modulus (1-3.66 MPa) that can resist the compression weight of 10,000 times of its own weight without deformation. Furthermore, the NFC-Si-T aerogels exhibit anisotropic thermal insulation performances with a low average thermal conductivity (0.028-0.049 W m-1 K-1). More importantly, the limited oxygen index of the NFC-Si-T reaches up to 42.6-51%, showing excellent flame-retardant performance. Therefore, the "robust-soft" anisotropic NFC-Si-T aerogels can be used as an advanced thermal insulation material for building thermal insulation applications.
