Claim 0:
1. A method for manufacturing a wrinkled graphene on a polymeric substrate, comprising:
providing a graphene unit;
inserting a carrier film and the graphene unit between a pair of rolls and rotating the pair of rolls in opposite directions to attach the carrier film to the graphene unit;
providing graphene by immersing the graphene unit in an etching solution;
inserting the graphene and a poly (4-styrene sulfonic acid)/polystyrene (PSS/PS) substrate between the pair of rolls and attaching the graphene to the PSS/PS substrate, the PSS/PS substrate comprising a PSS substrate and a PS substrate;
removing the carrier film from the graphene to provide a graphene/PSS/PS stack;
heating the graphene/PSS/PS stack wherein the PS substrate is shrunken to generate a wrinkled graphene (WGr);
inserting a polymeric substrate, the WGr and the PSS/PS substrate between the pair of rolls, and attaching the polymeric substrate onto the WGr by rotating the pair of rolls in opposite directions to form a polymeric substrate/WGr/PSS/PS substrate;
immersing the polymeric substrate/WGr/PSS/PS substrate in water to remove the PS substrate by dissolving the PSS substrate, and
providing a wrinkled graphene substrate on the polymeric substrate.
