NOVELTY - Preparation of temperature-strain dual-function sensing integrated breathable film involves (a) dissolving thermoplastic polyurethane particles in dimethylformamide/tetrahydrofuran mixed solvent, collecting thermoplastic polyurethane fibers on the surface of the aluminum film substrate to form two-dimensional mesh-like fabric-type thermoplastic polyurethane film, peeling off the prepared thermoplastic polyurethane film from the surface of aluminum substrate, (b) processing the thermoplastic polyurethane film prepared in the step (a) by plasma cleaning machine, soaking the treated thermoplastic polyurethane film in poly(4-styrenesulfonic acid) solution, drying, (c) disposing carbon nanomaterials and carbon particle aqueous dispersions, soaking the thermoplastic polyurethane film processed in step (b) in the carbon nano material-carbon particle dispersion, drying, (d) immersing the thermoplastic polyurethane film in conductive polymer solution added with dimethyl sulfoxide, and drying. USE - Preparation of temperature-strain dual-function sensing integrated breathable film. ADVANTAGE - The method can realize the simultaneous sensing of temperature and strain and meet the conditions of large strain. DETAILED DESCRIPTION - Preparation of temperature-strain dual-function sensing integrated breathable film involves (a) dissolving thermoplastic polyurethane particles in dimethylformamide/tetrahydrofuran mixed solvent to form uniform mixed solution, using electrospinning device to absorb the mixed solution, covering the surface of the collection device of the electrospinning device with aluminum film as deposition substrate, collecting thermoplastic polyurethane fibers on the surface of the aluminum film substrate to form two-dimensional mesh-like fabric-type thermoplastic polyurethane film, peeling off the prepared thermoplastic polyurethane film from the surface of the aluminum substrate, forming a self-supporting thin film structure, (b) processing the thermoplastic polyurethane film prepared in the step (a) by a plasma cleaning machine, soaking the treated thermoplastic polyurethane film in poly(4-styrenesulfonic acid) solution, taking it out, drying at room temperature, (c) disposing carbon nanomaterials and carbon particle aqueous dispersions, soaking the thermoplastic polyurethane film processed in step (b) in the carbon nanomaterial-carbon particle dispersion, drying, (d) adding 1-10 vol.% dimethyl sulfoxide in the conductive polymer solution in advance, immersing the thermoplastic polyurethane film in the conductive polymer solution added with dimethyl sulfoxide again, taking out the film and drying.
