Abstract
To obtain ideal flexible and high conductivity nanocomposites, 3 kinds of bacterial cellulose (BC) based nanocomposites were synthesized, including BC-SnO2, BC-polypyrrole (PPy) and BC-SnO2-PPy. The structures of these composites were compared via FTIR, XRD, TGA and FE-SEM. The conductivity and electrochemical properties were evaluated by CV test and EIS test. The resistance value of BC-SnO2, BC-PPy and BC-SnO2-PPy was 273.5 Ω, 57.9 Ω and 35.9 Ω, respectively, and conductivity was 0.077 S/cm, 1.152 S/cm and 7.246 S/cm, respectively. The bending tests showed the electrochemical properties kept stability at various bending deformations. Results here provide an easy, and environmentally friendly method to synthesize BC-SnO2-PPy which may have potential application as flexible, highly conductive material.
