Method for preparing titanium dioxide nanofiber ultraviolet light dependent resistor

Abstract

The invention belongs to the technical field of ultraviolet light dependent resistors and relates to a method for preparing a titanium dioxide nanofiber ultraviolet light dependent resistor. The method includes that firstly experiment parameters are controlled, an electrostatic spinning method is utilized to prepare TiO2/polyvinylpyrrolidone (PVP) composite nanofiber film, the TiO2/PVP composite nanofiber film is subjected to heat treatment in a muffle furnace to obtain a TiO2 nanofiber film, the TiO2 nanofiber film is placed on a plastic sheet, electrodes are fixed by electric conduction elargol, and a polydimethylsiloxane (PDMS) encapsulating adhesive is utilized for damp-proof protective encapsulation to obtain a light dependent resistor element. According to the method for preparing the titanium dioxide nanofiber ultraviolet light dependent resistor, the titanium dioxide light dependent resistor is safe and non-toxic, environment-friendly, raw materials are easy to obtain, the preparing process is simple, the cost is low, the market potential is large, and the service life is long.
