Abstract

Abstract: Three-dimensional poly(aniline- co -pyrrole)/thermally reduced graphene oxide (PAP/TRGO) composites with different amounts of TRGO have been fabricated via an oxidative polymerization method. The three-dimensional composite containing 20 wt% TRGO exhibits enhanced electrochemical performance as an electrode active material in supercapacitors in terms of its high specific capacitance value (287 F g −1 at 0.2 A g −1 ) and good rate capability (205 F g −1 at 20 A g −1 ). The assembled symmetric supercapacitor based on the PAP/TRGO20 composite shows excellent cyclic stability with a capacitance retention of 103% after 10, 000 charge-discharge cycles. These results represent a significant progress in the design of suitable binder-free electrode materials as electrochemical energy storage devices. Graphical abstract: Highlights: Poly(aniline- co -pyrrole)/TRGO composites were prepared via oxidative polymerization. TRGO content influenced the composite capacitance and electrochemical stability. The PAP/TRGO20 composite exhibited the most promising electrochemical performance. A capacitance retention of 103% after 10, 000 cycles was noticed for a symmetric device.
