▎ 摘　　要

NOVELTY - Preparation of graphene-based and fabric-like polyaniline supercapacitor includes performing chemical reduction of expanded graphite with polyester fabric in 0.5-1 mg/mL ethanol/isopropanol, dipping at 35-90 degrees C, drying, heating under water bath at 60-90 degrees C for 4-8 hours to obtain graphene/polyester fabric electrode, performing in-situ chemical polymerization of graphene/polyester fabric electrode with 0.1-0.5 M/L hydrochloric acid/sulfuric acid solution for 1-2 hours at 0-15 degrees C, adding 0.1-0.5 M/L ammonium persulfate, adjusting pH to 0, stirring for 5-90 minutes, and spraying surface. USE - Method for preparing graphene-based and fabric-like polyaniline supercapacitor. ADVANTAGE - The supercapacitor is inexpensive, and has simple preparation and excellent flexibility.
