doi:10.21127/yaoyigc20200014

Abstract

Abstract: Dried foam films (DFF) of graphene oxide (GO) has been prepared by dipping a titanium mesh in the solution of GO, and then it was reduced by electrochemical method. Next, the as-prepared water-containing reduced grapheme oxide (rGO) DFF film works as electrode for electrocpolymerization of aniline onto its surface for preparing a polyaniline/graphene monolith while the titanium mesh acts as the electron collector. The as-obtained composite film is binder-free and has highly surface area, conductivity, and can be used for supercapacitor electrode. Then network of plenty polyaniline nanoparticles formed on the surface of rGO film by electrochemical polymerization, which works as the material for pseudocapacitance. When the film is used as a supercapacitor electrode, the maximum specific capacitance is as high as 633.4 F g⁻¹ and the specific capacitance retains 75% of the initial after constant charge discharge 5000 cycles at current density of 10 A g⁻¹, indicating that the nanocomposite is a suitable active material for supercapacitors.

Key words: graphene, polyaniline, dried foam film, supercapacitors, electrode
