▎ 摘  要

NOVELTY - A graphene oxide solution is provided. The graphene oxide solution is frozen by growing along temperature gradient directional growth, and the frozen graphene oxide is subjected to ice sublimation, to obtain graphene oxide sponge. The graphene oxide sponge is heated in inert gas, and graphene oxide is reduced, to obtain graphene sponge. USE - Preparation of graphene sponge used for strain sensor (claimed).
