▎ 摘  要

NOVELTY - The preparation method of three-dimensional porous graphene foam material involves carrying out heat treatment on organic polymer industrial product in an inert atmosphere, and then graphitizing at 900-2500 degrees C for 1-5 hours to obtain three-dimensional porous graphene block, where the organic polymer industrial product is ultralight clay and/or paper clay. USE - The method is useful for preparing three-dimensional porous graphene foam material, which is useful in oil stain adsorption (claimed). ADVANTAGE - The method prepares three-dimensional porous graphene foam material with excellent hydrophobicity and mechanical strength.
