Abstract: A large-area wrinkled graphene substrate capable of being manufactured in a large-area, and a method for manufacturing the same is provided. A method for manufacturing a wrinkled graphene substrate includes: i) providing a graphene unit; ii) inserting a carrier film and a graphene unit between a pair of rolls and rotating the pair of rolls in opposite directions to attach a carrier film on the graphene unit, iii) immersing the graphene unit in an etching solution to provide graphene, iv) between a pair of rolls, graphene and poly(4-styrene sulfonic acid)/polystyrene (PSS/PS) substrate attaching graphene onto the PSS/PS substrate, v) attaching an ethylene vinyl acetate/polyethylene terephthalate (EVA/PET) substrate to wrinkled graphene on PSS/PS substrate by inserting EVA/PET and WGr/PSS/PS stack between the rolls, viii) removing the PSS/PS substrate by immersing PET/EVA/WGr/PSS/PS stack in water, and ix) providing a wrinkled graphene substrate on the EVA/PET substrate.
