Effects of Polypyrrole / Graphene Oxide Composites with Different Reaction Times on Electrochemical Performance

Updated time: 2020-04-15

【Summary】 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 com- posite material. The effects of different reaction times on the electrochem- ical 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
