▎ 摘  要

NOVELTY - A preparation method of graphene foam comprises dispersing graphene in a solvent to obtain a graphene solution, and soaking a decomposable template material in the graphene solution, taking out the template material coated by the graphene, removing the solvent by drying, and removing the template material to obtain the graphene foam. USE - The graphene foam prepared by the method is used in a battery electrode, in sustained release drug and as a hydrogen storage material (all claimed). ADVANTAGE - The method is more convenient to carry out and achieves mass production of graphene foam.
