Abstract
A method for forming a copper coated particles includes combining a precipitating agent with a solution comprising copper nitrate and particles to forming coated particles. The particles are cobalt oxide (CoO) or carbon black. The coated particles are washed to obtain washed coated particles, the washed coated particles are filtered to obtain filtered coated particles, the filtered coated particles are dried to obtain dried coated particles, and the dried coated particles are calcined to obtain the copper coated particles. The copper coated particles have a reflectivity of electromagnetic radiation in a visible spectrum that is less than or equal to 5%, and a reflectivity of electromagnetic radiation in a near-IR and LiDAR spectrum that is greater than or equal to 5%.
