▎ 摘　　要

NOVELTY - Graphene flakes comprises slurry mixed with 99% purified graphite and deionized water under high temperature and high pressure is manufactured through multiple compression-explosion processes, and the thickness is 3-5 nm, more than 1900S/cm electrical conductivity, 20-45 m2/g surface area, and 3 wt.% oxygen content. USE - Used as graphene flakes. ADVANTAGE - The graphene flakes and graphene polymer products can produce environmentally-friendly graphene. The graphene polymer film can effectively block antibacterial, sterilizing and electromagnetic waves. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) solid state graphene polymer master batch, prepared by dissolving 5 plus minus 0.5 wt.% graphene flake and liquid organic solvent, mixing to create a liquid graphene suspension, mixing graphene suspension and polymer so that the content of the graphene flakes is 0.1-10 wt.%, and drying; and (2) producing graphene polymer product, comprising producing graphene through multiple compression-explosion processes in a slurry mixed with 99% pure graphite and deionized water under high temperature and high pressure, mixing the graphene flakes with the polymer to prepare a solid graphene polymer masterbatch in which the content of the graphene flakes is 0.1-10 wt.%, and mixing graphene polymer master batch and base polymer so that the content of the graphene flakes is 0.03-1 wt.%, melting and extruding to produce graphene polymer products.
