Abstract:
PURPOSE: A method of coating the surface of inorganic powder particles with a silicon-carbon composite, and inorganic powder particles surface-coated with the silicon-carbon composite manufactured thereby are provided to form a thin and uniform coating film compared to a liquid coating method, to form a superhydrophobic silicon-carbon composite coating film having a high stability to ultraviolet rays, and to enable the silicon-carbon composite coating to be used as anti-oxidation layer of a sample. CONSTITUTION: A method of coating the surface of inorganic powder particles with a silicon-carbon composite comprises a step of mixing inorganic powder particles and solidified silicone organic polymers, and a step of heating the mixture. The inorganic powder particles are at least one selected from the group consisting of titanium dioxide, zinc oxide, zirconium oxide, copper, nickel, carbon fibers, and activated charcoal. The solidified silicone organic polymers are obtained by adding a curing agent in the silicone organic polymers. The silicone organic polymers are polydimethylsiloxane, polyvinylsiloxane, polyphenylmethylsiloxane, or their combination. The curing agent is organic peroxide. The heating is performed at 150-300 deg. C.
