▎ 摘　　要

NOVELTY - A graphene/organic composite particle comprises organic particle (1), graphene powder layer (2) and cover protective layer (3). The graphene powder layer is coated on the surface of the organic particle. The cover protective layer is coated on the surface of graphene powder layer. USE - Graphene/organic composite particle used as microjet printing forming material for producing graphene modified composite material or device. ADVANTAGE - The particle has simple preparation method, low production cost, and controllable thickness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene/organic composite particle comprising cooling organic particle; and subjecting graphene powder to low-temperature argon plasma treatment, adding organic particle and fused corundum grinding ball in batches, alternately adding to ceramic tank, mixing, ball milling, sieving, adding to spray coating apparatus, starting device until product reaches fluidized state, spraying surface with alcohol-soluble resin solution through two-phase flow nozzle, and hot air drying. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of graphene/organic composite particle. Organic particle (1) Graphene powder layer (2) Cover protective layer (3)
