▎ 摘  要

NOVELTY - A graphene powder material comprises graphene material and liquid-absorbent expanding material composite, where graphene surface is uniformly covered with liquid-absorbent expanding material such that the suction between adjacent graphene material and liquid-absorbent expandable material forms a barrier. The mass ratio of graphene material to liquid-absorbent expanding material is 1:0.01-1:10 and expansion coefficient of liquid-absorbent expanding material is greater than or equal to 50. USE - Graphene powder material. ADVANTAGE - The raw materials have good compatibility. The material greatly expands the realm of the graphene material powder in downstream product applications and successfully solves problem of industrial applications of graphene powder material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of graphene powder material comprising preparing 0.1-3% mass concentration aqueous slurry graphene material, weighing liquid absorbent expandable material, and adding to aqueous slurry to obtain intermediate slurry; and heat-drying, freeze-drying, spray-drying, or granulation-drying.
