Ultrasonic Assisted Synthesis of 2D-Functionalized Grapheneoxide@PEDOT Composite Thin Films and its Application in Electrochemical Capacitors

Poly(3,4-ethylene dioxythiophene) (PEDOT)@functionalized graphene oxide (FGO) hydrogel thin films were fabricated by simple sonochemical polymerization of EDOT with 1 wt% of FGO. The unique properties of the composites were investigated by FT-infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, cyclic voltammetry and impedance analysis. The potential utility of synthesized composites as electrodes for high-performance supercapacitors has been assessed. Sulfonated graphene oxide (SFGO)-PEDOT showed higher electrochemical performance and long-durability than that of carboxyl functionalized graphene oxide (CFGO)-PEDOT composite and pristine PEDOT. This composite satisfied the prerequisite of elongated cycle life mandatory for a capacitive energy storage device system.
