A composite film (CMP1) comprises graphene (GRF1) and a conformal layer (POLY1) of a polymer deposited on the graphene (GRF1). The composite film (CMP1) is produced by a method, which comprises: - depositing graphene (GRF1) on a substrate (S0), - forming a first polymer layer (POLY1) on the graphene (GRF1) by bringing a monomer (M1) into contact with the graphene (GRF1) such that the monomer (M1) polymerizes on the surface (SRF1) of the graphene (GRF1), and - removing the substrate (S0) from the graphene (GRF1), wherein the monolayer (GRF1) comprises a plurality of microscopic convex regions (CNX1), which are fully supported by the conformal polymer layer (POLY1).
