▎ 摘　　要

NOVELTY - The graphene efficient air filter screen has an active carbon fiber filter screen, non-woven net and a metal mesh. The metal mesh is paved with an active carbon fiber filter net and non-woven net. The metal net is coated with graphene. USE - Graphene efficient air filter screen. ADVANTAGE - The graphene using the air filtration net is provided with simple integral structure, simple technical steps, using the graphene super-high specific surface and special electrostatic adsorption ability, obstructs the smaller particles in the air to reach better purifying effect, to prevent bacterial growth. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene-efficiency air filter screen.
