Abstract

Graphical abstract: Highlights: Bacterial cellulose turned to conductive membrane by coating with polypyrrole. BC-PPy with conductivity of 3.9 S cm −1 and specific capacitance of 191 F g −1 . Conductive BC-PPy membrane to be applied as biosensor or energy storage devices. Abstract: The purpose of the current work was to produce conducting electroactive membranes from bacterial cellulose (BC) coated with polypyrrole (PPy) via in situ chemical polymerization of pyrrole at 4 °C using FeCl3 as oxidant agent. The electrical conductivity, tensile, thermal and electrochemical properties of BC-PPy membranes were investigated. The results revealed that the uniformly coating of PPy nanoparticles on the surface of BC template achieved high electrical conductivity of 3.39 S cm −1 and a specific capacitance of 191.94 F g −1 at 5 mv s −1 scan rate. The high conductivity and specific capacitance of the present BC-PPy membranes opens new potential applications for BC in various fields as biosensors, flexible electronics, or energy storage devices.
