Abstract

The invention belongs to the field of conductive thin film and relates to a method for preparing an even and transparent conductive thin film by using electrostatic spinning. A spinning solution is prepared from 0.1-1.0% of silver nanometer yarn, 0.1-1.0% of surface charge regulator, 1.0-5.0% of polyoxyethylene and the balance water. The method for preparing the even and transparent conductive thin film comprises the steps that the prepared spinning solution is added to a needle cylinder of an electrostatic spinning device, a substrate is placed under a needle of the electrostatic spinning device, and an initial thin film is prepared by the electrostatic spinning device; the initial thin film is placed on a heating stage to be heated, and then immersed in heated ethyl alcohol and water in sequence; finally after the thin film is dried, an ultimate transparent conductive thin film is obtained. The method is easy and fast, the transparent conductive thin film can be prepared on a conventional flat substrate and can also be prepared on an uneven or curved substrate, and the prepared transparent conductive thin film by using the method is excellent in performance and can be widely applied to various electronic devices.

Description

technical field [0001] The invention belongs to the field of conductive films and relates to a method for preparing uniform transparent conductive films by electrospinning. Background technique [0002] At present, in the field of consumer electronics, indium tin oxide (ITO) is the most commonly used electrode conductive material. However, the scarcity of indium content leads to its limited output and relatively high price; at the same time, the complex instruments and high temperature conditions required for its preparation, and its brittle characteristics all limit its wider application. Therefore, people have been looking for materials that can replace ITO. Among them, silver nanowires have attracted much attention due to their excellent performance and relatively cheap price, and are currently the most likely material to replace ITO and be commercialized. [0003] At present, the methods for preparing silver nanowire transparent conductive films mainly include spin coa...
