NOVELTY - A graphene layer producing method involves applying 0.25-5 wt.% graphene ink and 95-99.75 wt.% solvent that is butyl carbitol acetate to a substrate, and curing graphene ink layer at 100-160 degrees C, followed by applying 1-10 wt.% graphene filler comprising polymethyl polymethyl methacrylate or butyl, 90-99 wt.% butyl carbitol acetate to the ink layer by using spraying process. The layer is hardened at 100-160 degrees C, and controlling thickness of first layer to be less than 1000 nm. USE - Method for producing graphene layer on substrate.
