제목 High Power and Energy Densities of Supercapacitor Based on Three Dimensional Ion and Electron Pathways
초록 In this work, we present a simple and general method to fabricate free-standing macroporous-embossed chemically modified graphene (CMG) films, using sacrificial polystyrene (PS) particle templates we refer to as embossing process. The resulting embossed-CMG (e-CMG) films provide a three dimensional (3D) macropore network, a large surface area, and excellent mechanical integrity. In addition, the heterostructured 3D porous MnO2/e-CMG composite films prepared by nanoscale conformal coating of MnO2 dramatically increased the specific capacitance comparing to the homogeneous e-CMG film.
