▎ 摘　　要

NOVELTY - The film has a base layer whose side surface is provided with a negative oxygen ion powder layer that surface side is arranged with a graphene layer i.e. fiber layer. An outer surface layer i.e. non-woven fabric layer is covered with the graphene layer. A side part of the base layer is provided with an adhesive tape i.e. double-sided adhesive tape that is formed with a net-shaped structure. The adhesive tape divides the surface of the base layer into multiple negative oxygen ion generation regions. The negative oxygen ion powder layer is arranged in the negative oxygen ion generating regions. The graphene fiber layer is connected with a non-woven fabric layer i.e. hot melt and non-woven fabric layer. in flocking manner. USE - Air purifying negative oxygen ion releasing roof film for home decoration field. ADVANTAGE - The film disperses the negative oxygen ion in the room so as to effectively improve indoor air environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an air purifying negative oxygen ion releasing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the air purifying negative oxygen ion releasing roof film for home decoration field.
