A kind of ito conductive film

Abstract

The invention provides a novel ITO conductive film comprising a base material layer, and an optical adjustment layer, an ITO layer, a conductive adhesion layer, a copper conductor layer, and a conductive blocking layer, all of which are stacked on the upper surface of the base material layer. The thickness of the conductive adhesion layer is 1-100 nm. The thickness of the copper conductor layer is 50-800nm. The conductive blocking layer has a conductive function, and the thickness of the conductive blocking layer is 1-100nm. The surface resistance of the ITO layer is 80-400omega / square, and the change rate of the surface resistance is 0-20% after the ITO layer soaks in 1N hydrochloric acid for 3 minutes. According to the ITO conductive film provided by the invention, the copper conductor layer is directly made on the ITO layer, no adhesive is needed, and the problem of coiling is solved. Moreover, the conductive adhesion layer is added between the ITO layer and the copper conductor layer, and the conductive blocking layer is added on the copper conductor layer, so that the problem that the adhesion effect of copper and ITO is not good and oxidation can be easily caused is overcome effectively, the problems of adhesion and anti-oxidation can be solved, and the weather resistance of products is increased.

Description

Technical field [0001] The invention relates to a transparent conductive film, in particular to an ITO conductive film coated with copper on the surface. Background technique [0002] At present, more and more electronic devices such as mobile phones and tablet computers use touch screens. Touch screens are very popular and common as an input device. Therefore, the demand for transparent conductive films that are essential for touch screens is increasing. . Among them, resistive and capacitive touch screens are more commonly used. With the advancement of technology, various structures of capacitive touch screens continue to emerge.
