METHOD FOR PREPARING CONDUCTIVE HEAT-DISSIPATING GRAPHENE COATING MATERIAL USING SOL-GEL METHOD AND GRAPHENE OXIDE, AND CONDUCTIVE HEAT-DISSIPATING GRAPHENE COATING MATERIAL PREPARED THEREBY

摘要

The present invention provides a conductive heat-dissipating graphene coating material comprising (A) a graphene oxide sol, (B) a composite ceramic comprising alumina, titania and zirconia, (C) a colloidal silica, (D) a deflocculant, and (E) a silane coupling agent. The conductive heat-dissipating graphene coating material according to the present invention not only exhibits outstanding electrical conductivity and especially, thermal conductivity, but also overall excellent chemical-resistant properties and mechanical properties such as high-temperature heat resistance, pencil hardness, high corrosion resistance, hydrophilicity, and fouling resistance.
