▎ 摘　　要

NOVELTY - Preparing graphene dispersion involves performing homogenization on graphene powder, using a processing solvent to form a graphene paste, and performing a layer-thinning process on the graphene paste to form graphene dispersion. USE - Method for preparing graphene dispersion used as coating field, and important additive in products such as conductive coatings and auxiliaries, lithium ion electrode auxiliaries, anti-corrosion coating additives, and graphene heat spread films. ADVANTAGE - The prepared graphene dispersion has a two-dimensional structure formed by carbon atoms bonded with sp2 covalent bonds, reliable quality of products, low manufacturing cost, special properties such as a relatively high carrier mobility, hardness, thermal conductivity, and large surface area, so graphene has become a highly-valued research target in fields such as medicine, electronics, and optoelectronic components.
