▎ 摘　　要

NOVELTY - The preparation method involves (1) configuring a dispersing agent and an aqueous suspension of nano-inorganic materials, adding layered graphite to the aqueous suspension to obtain a layered graphite suspension, carrying out shear dispersion, preparing nano-inorganic material and graphene aqueous dispersion by high-pressure micro-jet homogeneous impact, and (2) spray-drying or centrifuging the nano-inorganic material and the graphene aqueous dispersion, and calcining at 300-800degreesC to obtain the graphene composite material. The layered graphite is selected from natural flake graphite, synthetic graphite, expandable graphite, expanded graphite, intercalated graphite, graphite nanosheet, electrochemically pretreated graphite, colloidal graphite, and highly oriented pyrolysis graphite powder. USE - Preparation method of graphene composite material (claimed) used in various fields such as thermal conductivity, supercapacitors, lithium batteries, electrocatalysis and fuel cells, and used in field of graphene application research. ADVANTAGE - The method is simple and mild, has short production time, high graphene yield, can quickly respond according to the application requirement, and reduces different factories. Different process production of graphene is different to generate interference to application effect, and has good physical performance and heat conducting performance. The graphene composite material prepared by the method has few graphene layers and the number of layers is concentrated. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a transmission electron microscope analysis result of the dispersion liquid containing nano-titania powder and graphene.
