▎ 摘　　要

NOVELTY - Preparing carbon nanotube-graphene composite foam comprises dispersing 5-20 mg/ml of ferrocene into an organic solvent at a low boiling point to obtain ferrocene solution, fully immersing, impregnating the solution to remove graphene, drying, placing the ferrocene solution into a microwave reactor using non-oxidizing protective gas, performing microwave treatment, and naturally cooling down at room temperature to obtain carbon nanotube-graphene composite foam. USE - The method is useful for preparing carbon nanotube-graphene composite foam (claimed). ADVANTAGE - The method simply and economically prepares the carbon nanotube-graphene composite foam with good hydrophobic and hydrophilic characteristics in an industrial manner.
