摘要（英）：

The invention discloses an electrostatic spinning nano-fiber film, and a preparation method and a finger detection method of the electrostatic spinning nano-fiber film. The finger detection method has the advantages of simplicity, rapidity, high sensitivity and no toxicity or harm, and dispenses with large instruments. The prepared fiber film has a wide range of practical objects, is rapid and convenient for operation, and is easy for mass production, and the raw material of the fiber film can be easily acquired. The invention mainly adopts the electrostatic spinning technology to prepare the polymer-based dye hybridization nano-fiber film, and the film can be used for direct fingerprint extraction and rapid fingerprint display at a certain temperature. The electrostatic spinning nano-fiber film disclosed by the invention is a polymer nano-fiber film in which dyes are evenly dispersed, wherein, the mass ratio of polymer and the dyes is 2-100 to 1, and the nano-fiber diameter is uniform and ranges from 50nm to 1,000nm.
