Title: POLYURETHANE FILM COMPRISING GRAPHENE AND PREPARATION PROCESS THEREOF.
Abstract:
A polyurethane film comprising a polyurethane resin and graphene, wherein the graphene is present in an amount of 1 to 30% by weight on the total weight of the film and consists of graphene nano-platelets, wherein at least 90% has a lateral dimension (x, y) of 50 to 50000 nm and a thickness (z) of 0.34 to 50 nm, wherein the lateral dimension is always greater than the thickness (x, y > z), wherein the C/O ratio is ≥ 100:1, and a preparation process thereof.
