Three-dimensional graphene/conducting polymer (3DGCP) composites have received significant attention in recent years due to their unique structures and promising applications in energy storage. With the structural diversity of graphene and π-functional conducting polymers via rich chemical routes, a number of 3DGCP composites with novel structures and attractive performance have been developed. Particularly, the hierarchical porosity, the interactions between graphene and conducting polymers as well as the their synergetic effects within 3DGCP...
