▎ 摘　　要

NOVELTY - The material has graphene substrate which is coated with graphene. The graphene coating surface is etched to form gradient structure with different surface roughness. The graphene substrate with the graphene coating are integrally formed or separately formed. The graphene has a spike-like structure. The density is gradually increased along with the increase of thickness. The etching process is carried out by a particle beam etching process or a laser engraving etching or physical engraving. USE - Solar radiation power material. ADVANTAGE - The graphene is good for visible and infrared bands. The absorption reach 100% absorption of solar heat and light. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing solar radiation power material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the gradient graphene coating after etching in solar radiation for generating material structure.
