Biological skin response halide luminescent fiber membrane as well as preparation method and application thereof

The invention discloses a halide luminescent fiber membrane with biological skin response as well as a preparation method and application of the halide luminescent fiber membrane. The composite material is prepared from a metal halide and an amino-containing polymer resin solution by using an electrostatic spinning technology, the amino-containing polymer resin solution comprises one or more of a thermoplastic polyurethane solution, a waterborne polyurethane solution or a high-temperature polyurethane solution; the chemical formula of the metal halide is ABX3; a in ABX3 is selected from Cs < + >, MA < + > or FA < + >, B is selected from Pb < 2 + >, Cu < 2 + >, Ag < + > or Sn < 2 + >, and X is selected from Cl , Br or I . The fiber membrane is high in recognition degree, high in sensitivity and good in stability; the preparation method has the advantages of easily available raw materials, simple operation and low cost, and can realize industrial large-scale preparation. In practical application, the
