Preparation method of silanized graphene heat-conducting coating
The invention relates to a preparation method of a silanized graphene heat-conducting coating, which aims to improve the firm chemical-bond binding force between the graphene coating and the ceramic, metal, glass and any other substrate and enhance the heat conductivity of the substrate material. The technical scheme is as follows: the method comprises the following steps: carrying out activating treatment on carboxyl group on graphene oxide, reacting the activated carboxyl group with amino group on silane to form an amido bond, applying a silanized graphene oxide solution onto a substrate surface by using a spraying mode instead of an immersion mode, and finally, firing at high temperature until the group on the silane is bonded with the substrate by the chemical bond, thereby effectively improving the adsorptive power between the graphene and substrate and further enhancing the heat conductivity of the substrate material by the aid of the high heat conductivity of the graphene. The silanized graphene heat-conducting coating can be applied to electric heating porcelain cups, electric heating kettles, endotherm knives and the like.
