▎ 摘　　要

NOVELTY - The laser-induced graphene type air filter has a polymer film formed by irradiating a laser in a scanning process, a base layer (1) made of a polymer material, and a porous carbon nanostructure layer (2) provided on the base layer in a state carbonized by the laser irradiation. The porous carbon nanostructure layer has a through portion in which a hole is formed and an induction portion (22) formed around the through portion by modulating the laser irradiation intensity. An inner circumferential surface defining the hole of the base layer is carbonized by the laser irradiation to form graphene. USE - Laser-induced graphene type air filter for a filter unit of an air purification apparatus (Claimed). ADVANTAGE - Dust collection performance is increased. Low weight and compact structure, and economical manufacturing of laser-induced graphene type air filter are ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a laser-induced graphene type air filter of an air purification apparatus. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a laser-induced graphene type air filter. Base layer (1) Porous carbon nanostructure layer (2) Penetration portion (21) Induction portion (22)
