Abstract
A thermal dissipation composite material comprising: a matrix including a polymer material; and composite particles distributed in the matrix, wherein the composite particles include a filler, and a thermally conductive material coated on the surface of the filler by an inorganic coating layer, and wherein the plurality of thermally conductive materials coated by the inorganic coating layer are connected to each other on the surfaces of the plurality of composite particles so as to establish a heat transfer network.
Claims5
A method of manufacturing a thermal dissipation composite material, the method comprising:
- stirring sodium silicate as an inorganic binder with a nonpolar solvent, wherein the inorganic binder includes a first OH functional group, and wherein the nonpolar solvent includes toluene and xylene;
- preparing a first mixture by mixing the inorganic binder, the nonpolar solvent, and a filler;
- preparing a second mixture by mixing a thermally conductive material with the first mixture;
- thermally treating the second mixture at between 600° C. and 900° C., thereby curing the inorganic binder and preparing a composite particle, wherein the composite particle comprises a particle of the filler having a surface coated with the thermally conductive material and an inorganic coating layer formed by curing the inorganic binder;
- and
- preparing the thermal dissipation composite material by mixing the composite particle and a polymer material with each other.
