NOVELTY - Smart textile comprises fabric and spiropyran-conductive substrate coating attached to surface of the fabric; the mass ratio of spiropyran to conductive substrate in the spiropyran-conductive substrate coating is 1-40:60-99. USE - The smart textile is used as textile sensor (claimed). ADVANTAGE - The smart textile: has ultraviolet radiation sensing function, and achieves the purpose of monitoring ultraviolet radiation information in the environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing smart textile comprising carrying any one of process one and process two; (process one): grinding and mixing spiropyran and graphene oxide powder when conductive substrate is reduced graphene oxide, to obtain a mixed powder; mixing the mixed powder with water to obtain dispersion liquid; soaking the fabric in dispersion liquid, taking out the soaked fabric for padding treatment, drying and performing reduction treatment to obtain smart textiles; (process two): grinding and mixing the spiropyran and the metal material when the conductive substrate is metal material, to obtain mixed powder; mixing the mixed powder with water to obtain a dispersion liquid; soaking fabric in dispersion liquid, taking out soaked fabric for padding treatment, and drying to obtain smart textile.
