NOVELTY - Preparation of ultrathin ultra-flexible graphene electroconductive thin film involves laminating graphene/metal foil graphene layer to film, forming ultra-thin ultra-flexible target substrate and back film composite, cutting, pre-shrinking, forming ultra-thin, ultra-flexible target substrate supported by backsheet, transferring dried film/graphene-containing layer on backsheet-supported ultra-thin superflexible target substrate, forming film/graphene/ultra-thin substrate/back film, removing adhesive film and back film, and obtaining graphene/ultra-thin substrate. USE - Preparation of ultrathin ultra-flexible graphene electroconductive thin film (claimed). DETAILED DESCRIPTION - Preparation of ultrathin ultra-flexible graphene electroconductive thin film involves laminating graphene/metal foil graphene layer grown by chemical vapor deposition method to a film, forming structure comprising film/graphene/metal foil, removing metal foil to form film/graphene-containing structure, drying, forming ultra-thin ultra-flexible target substrate and back film composite, cutting, pre-shrinking, forming ultra-thin, ultra-flexible target substrate supported by backsheet, transferring dried film/graphene-containing layer on the backsheet-supported ultra-thin superflexible target substrate, forming film/graphene/ultra-thin substrate/back film, removing adhesive film and back film, and obtaining graphene/ultra-thin substrate.
