▎ 摘　　要

NOVELTY - Preparing polypyrrole/silver/graphene oxide composite material involves adding pyrrole and silver nitrate solution to the graphene oxide dispersion in sequence to mix, and placing the obtained mixed solution under ultraviolet light. The oxidation-reduction reaction is performed to obtain a polypyrrole/silver/graphene oxide composite material. USE - Method for preparing polypyrrole/silver/graphene oxide composite material used for supercapacitors (claimed). ADVANTAGE - The method enables to prepare polypyrrole/silver/graphene oxide composite material improves the electrochemical performance of polypyrrole, increases the yield of polypyrrole and silver, provides structural support during long-term cycles, and prevents the problem of poor cycle stability caused by the collapse of the polypyrrole structure.
