[Abstract]:Zinc tin oxide and lead sulfide as new generation semiconductor materials are widely used in solar cells and sensors due to their excellent photoelectric properties and Guang Min properties, while polyimide (Pi) thin films have excellent mechanical properties. Polymeric thin films with thermal stability, chemical resistance and electrical properties are selected as substrates including zinc tin oxide and lead sulfide inorganic functional layer flexible composite films. The application range of semiconductor composite films can be extended. In this paper, hydrolysis method is used. Polyimide / zinc oxide / tin oxide composite films were prepared by in situ and doping methods. Polyimide / lead sulfide composite films were prepared by ion exchange and interfacial precipitation reaction. The structure and surface morphology were characterized by the following work: 1. The polyimide / polyamide acid / polyamide acid doped metal salt was used as the matrix material. Polyimide composite films containing zinc oxide and tin dioxide were prepared by hydrolysis / in situ / doping method. The crystalline composition of inorganic compounds on the surface of the films was determined by X-ray diffraction. The surface morphology of inorganic functional layer on the surface of the film was observed by scanning electron microscope, and the composition of the elements on the surface of the film was obtained by energy dispersive analysis. It was determined that the ion-exchange solution with ethanol as the solvent was more favorable for the target ion loading on the surface of the polyimide film, and the metal ion radius was also explored. The effect of valence state on the surface of polyimide film was studied. The polyimide / lead sulfide composite film was prepared by alkali hydrolysis, ion exchange and heat treatment. The crystalline form of inorganic compound on the surface of polyimide film was determined by X-ray diffraction. The surface morphology of inorganic functional layer on the surface of polyimide film was observed by scanning electron microscope, and the heat treatment temperature was investigated. Effects of heat treatment time and heat treatment atmosphere on the surface morphology of inorganic functional layer on the surface of composite films.
