▎ 摘 要
NOVELTY - A lithium ion battery graphene orientation flexible packaging film comprises support body and a wrapping material, where the support body is formed by orienting a graphene functional masterbatch in a polyolefin and the graphene functional masterbatch is modified by graphene or graphene oxide to obtain functionalized graphene, the functionalized graphene is blended with polyurethane or polyacrylate to obtain functionalized graphene and polyurethane and the mass ratio is 1:2-20, the mass ratio of functionalized graphene to polyacrylate is 1:2-30 and flexible packaging film has a thickness of 1-300 mu m. USE - Lithium ion battery graphene orientation flexible packaging film. ADVANTAGE - The film has excellent barrier property and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing lithium ion battery graphene orientation flexible packaging film, which involves using organically modifying graphene or graphene oxide to obtain functionalized graphene and blending functionalized graphene with polyurethane or polyacrylate to obtain a graphene functional masterbatch, blending the functional masterbatch with the polyolefin, extruding and applying ultrasonic irradiation to obtain a highly ordered aligned oriented graphene during melt extrusion and casting into a film and combining the film containing oriented graphene with the outer layer of nylon or polyethylene terephthalate to obtain the finished product.
