GRAPHENE COMPOSITE POWDER FORM MATERIAL AND METHOD FOR MAKING THE SAME

摘要

The present invention provides a graphene composite powder form material that is suitable for industrialized application. The graphene composite powder form material is composited by graphene materials and a high-molecular compound. The high-molecular compound is uniformly coated on surfaces of the graphene material. Any adjacent graphene materials are separated by the high-molecular compound. An apparent density of the graphene composite powder form material is larger than or equal to 0.02 g/cm3. Under an external pressure, the graphene materials in the graphene composite powder form material do not re-stack, and can be easily restored to original form, which benefit the storage and transportation. Besides, the graphene composite powder form material has a good compatibility in other material systems, which greatly broadens the application fields in the downstream products and successfully solves the problem in industrial application. The present invention also provides a method for making the graphene composite powder form material.
