NOVELTY - Method for producing a graphene sensor element involves (a) forming a graphene layer on a growth substrate, applying a fluoropolymer coating layer over the graphene layer, removing the growth substrate, transferring the graphene and fluoropolymer coating layers onto a transfer substrate such that the graphene layer is arranged on the transfer substrate and the fluoropolymer layer is arranged on the graphene layer, and removing the fluoropolymer coating layer, or (b) forming a graphene layer on a growth substrate, functionalizing the graphene layer, applying a fluoropolymer coating layer over the graphene layer, removing the growth substrate, transferring the graphene and fluoropolymer coating layers onto a transfer substrate, and removing the fluoropolymer coating layer. USE - The method is useful for producing graphene sensor element for analyzing gas sample. ADVANTAGE - The removal process in the method leaves minimal residue or deformation on graphene surface.
