▎ 摘 要
NOVELTY - Producing graphene oxide paper, comprises (a) preparing graphene oxide colloid solution by dispersing graphene oxide powder in dispersion medium, and (b) producing graphene oxide paper by dropping the obtained graphene oxide colloid solution from a thermostat through sound wave. USE - The paper is useful in electrode separation membrane of secondary battery and supercapacitor. ADVANTAGE - The method controls thickness of the size and paper; produces flexible, porous, chemically and electrochemically stable paper having excellent dielectric; maintains constant temperature; and uniformly disperses graphene oxide powder.
