Abstract : In this paper, we report a wet chemical synthesis of polyaniline – platinum nanocomposite and the fabrication of a flexible supercapacitor. Capacitive properties of the synthesized materials were analyzed using cyclic voltammetry, EIS, and galvanostatic charge–discharge. The high areal capacitance of 102 mF cm−2 was obtained for polyaniline platinum nanocomposite with 10 wt% graphite and 10 wt% PTFE binder. The prototype of a parallel plate supercapacitor was fabricated with an optimum concentration of HCl incorporated cellulose paper as the dielectric medium. Polyaniline –platinum composite exhibited high specific capacitance of 280F g−1, with characteristic breakdown potential of 1.0 V, a specific energy density of 2.46 W h g−1, and a specific power density of 0.15 W g−1. It also exhibits high elasticity and flexibility. The capacitance is not altered while applying strain which indicates the applicability of polyaniline and its nanocomposites for flexible electronics.
