▎ 摘　　要

NOVELTY - The filter has an activated carbon fiber filter, a glass fiber mesh layer, a nylon mesh layer, a graphene coating. The graphene coated metal mesh and filter support frame are provided. A nylon mesh layer is arranged on the filter support frame. A nylon fiber mesh layer is provided on the nylon mesh layer. An activated carbon fiber mesh is arranged on the glass fiber mesh layer. A graphene-coated metal mesh is provided on the activated carbon fiber web. The graphene coated metal mesh is sprayed with a graphene layer. USE - Graphene-based indoor air purifier filter. ADVANTAGE - The overall structure is simple. The process steps are simple. The filtration is carried out by coarse filtration, medium efficiency filtration and high-efficiency filtration structure, which enhances the screening and diffusion of small dust particles, can block smaller particles in the air, and achieve better. The effect is purified and prevent bacterial growth. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the graphene-based indoor air purifier filter.
