▎ 摘　　要

NOVELTY - Light-homogenizing composite film comprises base material, light homogenizing film fixed on one side of the base material and diffusion film, which is fixed on the other side of base material. The light homogenerizing film is coated on the side of a base material by a light-hydrogen liquid, and the light-graphene film is obtained by curing. The raw materials of the light graphene liquid includes a film-forming substance resin, a polyurethane emulsion, a scattering particles, a leveling agent pigment, a crosslinking agent, a film forming substance resin and a polyuran emulsion. USE - The light homogenizing composite film is useful in an optical film, where the optical film is used in a light-emitting device. ADVANTAGE - The light homogenizing composite film has uniform light composite film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the uniform light composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional schematic diagram of the uniform light composite film.
