▎ 摘　　要

NOVELTY - The graphene based touch-sensitive film has a film substrate (1) and a polyurethane layer (2). The polyurethane layer is distributed on one side surface of the film substrate. The polyurethane layer is doped with graphene microspheres (3). The surface length of graphene microspheres in the polyurethane layer is 0.01-0.1 mg/m2. USE - Graphene-based touch sensitive film. ADVANTAGE - The laminating speed of the film on the surface of substrate can be increased, while reducing energy consumption of the coating process and improving the production efficiency of the film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene-based touch sensitive film. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene-based touch sensitive film.
