Composite transparent conductive film and preparation method thereof

Abstract

The invention discloses a preparation method of a composite transparent conductive film and application thereof in antistatic electricity. The composite transparent conductive film comprises a transition layer, a conductive layer and a protective layer, wherein the transition layer is formed on a glass or plastic surface substrate and is a polyurethane acrylate or polysiloxane coating; the conductive layer is one of an ITO film, an AZO film, an IZO film, a TiO2 film, a GAO film and a ZAO film, and is deposited on the transition layer; the protective layer is deposited on the conductive layer,and is one of silicon oxide, titanium nitride and silicon nitride. According to the invention, a problem that electrostatic charges are accumulated on a surface of a transparent piece is solved whilesalt spray and moist heat resistances and other environmental properties of the conductive layer are improved by controlling the thickness and density of the protective layer.

Description

technical field [0001] The invention relates to a composite transparent conductive film and a preparation method thereof, belonging to the field of antistatic technology. Background technique [0002] Transparent plastic surfaces, such as the electronic industry and aircraft transparent parts, are prone to charge accumulation, resulting in product failure. The traditional method is to wet-coat antistatic paint on the surface of the product to avoid the accumulation of static electricity. Antistatic coating itself is a relatively mature product, and there are many related researches. These coatings often achieve antistatic effect by adding conductive fillers or conductive polymers. For transparent plastic surfaces, light transmittance is one of the most important properties of the product, and the addition of conductive fillers or conductive polymers in antistatic coatings greatly reduces the light transmittance of the product. Moreover, antistatic fillers are less stable, ...

AI Technical Summary

Problems solved by technology

For transparent plastic surfaces, light transmittance is one of the most important properties of the product, and the addition of conductive fillers or conductive polymers in antistatic coatings greatly reduces the light transmittance of the product

Moreover, the stability of antistatic fillers is poor. In special environments, such as high humidity, high heat or salt spray, antistatic components are prone to failure.

[0003] At present, there are few transparent antistatic coating products on the market, and the performance of many products cannot meet the requirements for use
