▎ 摘　　要

NOVELTY - Manufacture of graphene oxide containing liquid involves dissolving frozen mixture of oxidation graphite, water or water containing solution with graphene oxide and freezing. USE - Manufacture of graphene oxide containing liquid used for manufacture of graphene oxide porous component (claimed). Uses include but are not limited to electroconductive composite material, biosensor, transistor and energy storage material. ADVANTAGE - The method enables manufacture of graphene oxide containing liquid capable of providing graphene oxide porous component which is 3-dimensional porous component having pores between graphene oxides. Dispersion or solution of graphene oxide particles having larger diameter obtained by ultrasonic waves is used for graphene oxide preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene oxide porous component, which involves freeze-drying the water or water containing solution containing graphene oxide.
