MANUFACTURING METHOD FOR COPPER OXIDE NANOSTRUCTURES WITH HIGH SOLAR ABSORPTION AND LOW THERMAL EMISSION

摘要

The present invention relates to high solar absorption and a producing method of a copper oxide nano-structure for low emitting solar heat, wherein the producing method comprises: a step of preparing copper (Cu); a step of coating nano-particles on a surface of the copper; a step of producing a copper oxide by oxidizing the surface of the copper coated with the nano-particles; and a step of removing the nano-particles coated on the surface of the copper oxide. Absorption rate of ultraviolet rays-visible rays by oxidizing the surface of the copper is increased and emitting rate of infrared rays is decreased. The opper oxide nano-structure for low emitting solar heat can be obtained by simple chemical oxidation in a general oxidation apparatus and the temperature.
