摘要
Graphene oxide(GO)was prepared using the modified Hummers method and used as a template for polypyrrole.Polypyrrole was polymerized in situ on the surface of GO to finally obtain the polypyrrole/graphene oxide composite material.The effects of different reaction times on the electrochemical performance of polypyrrole/graphene oxide in the second step were studied.It was obtained that the composite material had optimal properties when the reaction time was 24 h.
