Carbon fiber‐embedded bacterial cellulose/polyaniline nanocomposite with tailored for microbial fuel cells electrode

Abstract

Microbial fuel cells (MFC) are of great interest for new sources of renewable energies from the waste of biomass and debris. This work aimed was to develop an anode electrode of the carbon fiber‐embedded of bacterial cellulose/polyaniline (CF/BC/PANI) nanocomposite for MFC applications. For this purpose, carbon fiber was wrapped onto bacterial cellulose (BC) fibers network during the BC synthesis. The CF/BC/PANI was obtained by polyaniline polymerization on the BC nanofibers as a scaffold. To characterize the electrode, scanning electron microscopy, Fourier‐transform infrared spectroscopy, X‐ray diffraction, and thermogravimetric analysis analysis were carried out. The electrical conductivity was determined by measuring the resistivity. MFC using the CF/BC/PANI electrode was monitored and the maximum current density generated was 0.009 mA/cm2. The results obtained from the CF/BC/PANI demonstrate great potential for the use as an MFC electrode, as well as a microenvironment favorable to a microbial biofilm formation.

Continuous fiber extruder for desktop 3D printers toward long fiber embedded hydrogel 3D printing

“…For example, short and dispersed hydroxypropyl cellulose bipolymer fibers can be embedded into polyvinyl alcohol (PVA) gel to enhance its ionic conductivity [9] . Similarly, hydrogel components can be cast with nanofibers for structural reinforcement [10] , [11] . In the field of plastic 3D printing, the concept of continuous fiber reinforcement has been implemented to significantly improve the tensile strength of printed parts.…”

Effect of glycerol on electrical conducting of chitosan/polyaniline blends

“…This polymer has a wide range of application (light-emitting diodes, plastic batteries, switchable membranes, sensors, energy storage devices, anti-static and anti-corrosion coating materials), and has high environmental stability; low cost of the monomer (aniline); high yield easy synthesis; adsorbent properties; as well as modification of mechanical, electromagnetic and solubility properties due to doping acid. 8,9,[14][15][16][17][18] PANI has different oxidation states controlled by oxi-reduction processes, in which protonation and deprotonation occur due to the addition of acids and alkaline solutions. 12,19 Many recent works of Cs/PANI blends carried out the in-situ polymerization of PANI associated with chitosan generating a powder with the ability to adsorb materials such as dyes.…”
