▎ 摘　　要

NOVELTY - A photo-catalytic graphene fiber includes graphene fiber as a substrate whose surface is coated with a layer of protective glue with a thickness of 7-15 mu m. The protective glue is coated with a layer of 3-7 mu m thick photocatalytic coating. USE - Photo-catalytic graphene fiber for use in adsorption and purification of toxic and harmful gases such as formaldehyde, toluene, xylene, ammonia, radon, total volatile organic compounds and other harmful substances in air. ADVANTAGE - The photo-catalytic graphene fiber has automatic removal of surface air pollutants and self-cleaning properties, excellent long-lasting performance, excellent catalytic bactericidal effect, and does not produce secondary pollution.
