Optimization of In-situe electrodeposition of Graphene/Polyaniline Composite Film for high-performance supercapacitor applications

This work describes optimization of a fast one-step electrochemical synthesis of graphene/polyaniline (PANI) composite films using graphite oxide (GO) and aniline as the starting materials on FTO substrate. Ramman confocal microscopy and Atomic force microscopy results demonstrated that the graphene/PANI composite film was successfully synthesized. The obtained graphene/PANI composite film showed high conductivity, good adhesion, and fast redox properties and had perfect layered and uniform structures. The electrochemical performance was evaluated by cyclic voltammetry. Electrochemical experiments indicated that the composite film had high performances and could be widely used in applied electrochemical fields as a super conductive electrode for sensor and battery applications.
