Preparation via flocculation of reduced graphene oxide/cationic polyacrylamide composites and their electrochemical properties†
Abstract
Composites of reduced graphene oxide (RGO) and cationic polyacrylamide (CPAM) are prepared through a facile method. The effect of CPAM content on the specific capacitance of the composite is investigated. Compared with the pure RGO, the composite shows a relatively high capacitance, due to the fact that CPAM improves the wettability and surface area of RGO.
