NOVELTY - Preparing high thermal conductivity graphene coating for heat sink comprises (a) configuring a graphene solution, where the mass ratio of graphene to solvent in the graphene solution is 1:20-1:100, adding a dispersing agent to the graphene solution, dispersing, until a uniform and stable graphene dispersion is formed, where the mass ratio of graphene to dispersant is 1:0.001-1:0.01, and (b) weighing adhesives and thickeners and adding to the graphene dispersion in step (a), dispersing, until a stable homogeneous slurry having a viscosity of graphene, where the mass ratio of graphene to adhesive is 1:0.2-1:0.8, where the mass ratio of graphene to thickener is 1:0.05-1:0.3, taking the graphene slurry in step (b) uniformly using to the surface of the heat dissipating member of the heat sink and drying. USE - The method is useful for preparing high thermal conductivity graphene coating for heat sink. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of the high thermal conductivity graphene coating in a heat dissipating component of a heat sink.
