Preparation of flexible and free-standing polypyrrole/graphene film electrodes for supercapacitors

Abstract

A free-standing polypyrrole/graphene film (PGF) electrode with an excellent electrochemical performance was obtained using spin coating and hydrothermal methods.

Polypyrrole micro/nanostructures and their soft materials in versatile forms: construction and applications

“…Free-standing PPy/graphene films can be facilely prepared and thus represents a typical flexible electrode material. 129–131 As reported by Li et al , 129 graphene films with PPy deposited on one side exhibited a specific area of 455 F g −1 at 1 A g −1 . In some cases, PPy works together with PANI as electrode materials, where the much higher pseudocapacitance of PANI is beneficial for improving the energy storage ability.…”
