▎ 摘  要

NOVELTY - A wearable conductive gas thin film sensor comprises a flexible substrate and a gas sensitive material layer formed on the flexible substrate. The gas sensitive material layer contains two-dimensional nanomaterials and material composed of conductive polymers. The two-dimensional nanomaterial is graphene, molybdenum disulfide, black phosphorus and/or MXene. The conductive polymer is polyaniline, polypyrrole, polythiophene and/or polyphenylene acetylene. USE - The wearable conductive gas thin film sensor is used in ammonia gas, nitrogen dioxide, and hydrogen sulfide gas sensing (claimed). ADVANTAGE - The film sensor has a three-dimensional network-shaped two-dimensional nano material/conductive polymer composite structure, good flexibility, and good gas sensing performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of film sensor comprising preparing aqueous solution of two-dimensional nanomaterials; mixing and dispersing first acidic aqueous solution and polymerized monomer and second mixing and dispersing with aqueous solution of the two-dimensional nanomaterial; second mixing and dispersing with oxidant; contacting the mixed solution containing polymerized monomers and two-dimensional nanomaterials with the oxidant dispersion solution and polymerizing; and transferring to a flexible substrate and drying. The two-dimensional nanomaterial is reduced graphene, molybdenum disulfide, black phosphorus and/or MXene. The polymerized monomer is aniline, pyrrole, thiophene and/or phenylacetylene.
