▎ 摘　　要

NOVELTY - Interfacial polymerization for synthesizing sulfonated-graphene and polypyrrole nanocomposites, is claimed. USE - Interfacial polymerization for synthesizing sulfonated-graphene and polypyrrole nanocomposites used as electrode material for supercapacitor (all claimed) for use in electrochemical energy storage device applications. ADVANTAGE - The method enables interfacial polymerization for synthesizing sulfonated-graphene and polypyrrole nanocomposites having excellent electroconductivity, stability and electrochemical reversibility of 500 charging/discharging cycles. The supercapacitors produced using the composite are safe, economical and environmentally-friendly and have high power density and excellent durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite, which is characterized by Fourier transform infrared spectrometer (FTIR), Raman spectroscopy, X-ray diffraction (XRD), Scanning electron microscope (SEM), four probe method, cyclic voltammetry (CV) and Galvanometric charge-discharge study.
