Coating composition for thermal emission using cnt and heat radiator structure

PURPOSE: A coating composition for thermal emission using a carbon nanotube-graft-siloxane polymer is provided to ensure excellent thermal emission compared with existing heat resistant coating agent or thermally emissive coating agent, and to improve adhesion, thermal conductivity, surface area, corrosion resistance and conductivity. CONSTITUTION: A coating composition for thermal emission using a carbon nanotube-graft-siloxane polymer into which a functional group is introduced comprises a carbon nanotube-graft-siloxane polymer selected from functional groups(-COOH, -COOCH3, -COCl, -OH, -NH2) and a polymer resin. The carbon nanotube is a multi-walled carbon nanotube with 10~20 micrometer length.
