Conductive nanocomposite membranes of polypyrrole/bacterial cellulose (PPy/BC) were
fabricated in situ by oxidative polymerization of pyrrole with iron (III) chloride as an oxidant and BC as a template. The morphology of the PPy/BC membrane indicated that PPy
nanoparticles deposited on the BC surface connected to form a continuous nanosheath
structure by taking along the BC nanofiber. The flexible PPy/BC membrane obtained with
the optimized reaction condition exhibited a high electrical conductivity of 3.9 S cm1,
which was hardly affected by bending stress. The PPy/BC membrane could be directly used
as flexible supercapacitor electrodes, with a maximum discharge capacity of 101.9 mA h g1 (459.5 F g1) at 0.16 A g1 current density. The capacity decreased with charge/discharge cycling, which is attributed to mechanical degradation of PPy as evidenced by scanning electron microscopy (SEM).
