Abstract

The invention provides a radio frequency (RF) plasma transparent conductive film. A base material is a polyethylene terephthalate (PET) film, the front face of the PET film is coated with a hardened coating, and the surface of the hardened coating is coated with a polyethylene (PE) protective film; and an RF plasma treatment layer is formed on the back face of the PET film, and a transparent conductive layer is sputtered on the RF plasma treatment layer and is coated with the PE protective film. In the transparent conductive film, one hardened coating is saved, and the RF plasma treatment layer is added, so that a reliable adhesion effect still exists between the transparent conductive layer and the PET film, the resistance value of the transparent conductive film still can keep high properties of uniformity and stability even if the transparent conductive film is subjected to high-temperature tempering, and the transparent conductive film can be widely applied to the aspects of touch panels, electronic games, child teaching machines, intelligent mobile phones, tablet personal computers (PCs) and the like.

Description

technical field [0001] The invention relates to a conductive composite material, in particular to a transparent conductive film prepared by radio frequency plasma technology. Background technique [0002] Transparent conductive film is an important material for preparing solar cells, liquid crystal displays and other devices. Transparent conductive film is formed by covering a transparent conductive layer on a transparent substrate. In order to improve the interface adhesion between the substrate and the conductive layer, it is often necessary to A layer of hardened coating is added between the substrate and the transparent conductive layer. The hardened coating needs to be cured under high temperature conditions. However, during the high temperature treatment process, the uneven distribution of molecular structure on the surface of the substrate will cause scattering phenomena, forming " "Rainbow pattern" further affects the visual effect and light transmittance of the prod...
