Claim 12:
13. A dual-phase thermal composite coating (TCC) for enhanced thermal conductivity and reduced deposit accumulation in a throttle body of an engine of a vehicle, the dual-phase TCC comprising:
a first material comprising one of parylene, polyesters, polyurethane, polyurea, polyarylate, polyethylene, epoxy, polyoxymethylene, polypthaldamide, polyamide, polyphenylene sulfide, polyether ether ketone, polyether ketone, polyimide, polysiloxane, polydimethylsiloxane, poly(methyl methacrylate), methyltrimethoxysilane, and polyflorocarbons, the first material comprising between 10 weight percent (wt %) and 90 wt % of the dual-phase TCC;
a second material comprising one of copper, zinc, aluminum, gold, silver, cobalt, manganese, carbon black, graphene, AL-bronze, aluminum silicates, SiO2, CuO, ZnO, TiO2, MoS2, and Al2O3, the second material comprising between 10 wt % and 90 wt % of the dual-phase TCC,
wherein the dual phase TCC has a contact angle of between 100 degrees (°) and 160° and a thermal conductivity of at least 0.3 W/mK.
