Preparation method for silver nano wire transparent conductive film capable of preventing corrosion of hydrogen sulfide gas

Abstract

The invention discloses a preparation method for a silver nano wire transparent conductive film capable of preventing corrosion of a hydrogen sulfide gas. The method comprises: scratching or sparying a silver nano wire colloid on an appropriate substrate to obtain a low-conductivity silver nano wire transparent conductive film; then carrying out post treatment of high temperature, high voltage and the like to obtain a high-transparency high-conductivity silver nano wire transparent conductive substrate; and then preparing a protective agent solution, diluting the protective agent solution in a large proportion, according to the type and size of the substrate selected for the silver nano wire film, selecting an appropriate spraying instrument or a spin coating instrument, preparing a protective layer of a thin layer on the surface of the substrate film, and finally, solidifying the protective layer through natural drying, heating by use of a heating plate or blow-drying by use of a blower. The silver nano wire transparent conductive film prepared by use of the method provided by the invention can prevent corrosion of gases such as the hydrogen sulfide gas and the like, can prevent scratches and has good conductivity and transmittance through a 3M adhesive tape and a pencil scratch test. The operation is simple, the cost is low, and large scale production can be carried out.

Description

technical field [0001] The invention relates to a preparation method of a silver nanowire transparent conductive film, in particular to a preparation method of a silver nanowire transparent conductive film resistant to hydrogen sulfide gas corrosion. Background technique [0002] In recent years, due to its better characteristics than ITO, silver nanowires have shown good prospects in the practical application of transparent electrodes, touch screens, solar cells and other small devices. In the future, the silver nanowire transparent conductive film will also be used for large devices such as game consoles and touch screens above 46 inches. [0003] There are various preparation methods for the silver nanowire transparent conductive film, such as scraping method, spraying method and so on. However, in practical applications, the silver nanowire transparent conductive film is easily corroded by corrosive gases (especially hydrogen sulfide gas) in the air and turns yellow and...

AI Technical Summary

Problems solved by technology

However, in practical applications, the silver nanowire transparent conductive film is easily corroded by corrosive gases (especially hydrogen sulfide gas) in the air and turns yellow and black, which leads to a decrease in its light transmittance and conductivity, and affects the continuation of the conductive film. use

At present, there is no report on a simple method for preparing a silver nanowire transparent conductive film that is resistant to hydrogen sulfide gas corrosion.
