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
The present invention relates to a kind of conducing composite material, relate in particular to a kind of nesa coating that uses the preparation of radio frequency plasma technology.
Background technology
Nesa coating is the preparation solar cell, the important materials of devices such as LCD, nesa coating is to cover transparency conducting layer to form on transparent base, in order to improve the interfacial adhesion power between base material and the conductive layer, often need between base material and transparency conducting layer, add one deck hardening coat, this hardening coat need could solidify under hot conditions, but in high-temperature process, the molecular structure skewness of substrate surface will produce scattering phenomenon, form " rainbow line " and then influence the visual effect and the light transmittance of product, in addition, the various materials of hardening coat use, solvent has also increased the manufacturing cost of product.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of nesa coating of radio frequency plasma is provided.
Purpose of the present invention is achieved through the following technical solutions:
The nesa coating of radio frequency plasma, base material are the PET film, characteristics: the front of described PET film scribbles hardening coat, and the hardening coat surface is covered with the PE diaphragm; The back side of described PET film is formed with RF plasma treatment layer, and sputter has transparency conducting layer on the RF plasma treatment layer.
Further, the nesa coating of above-mentioned radio frequency plasma is covered with the PE diaphragm on the described transparency conducting layer.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Adopt the radio frequency plasma technology that base material is carried out surface treatment, not only can improve the chemical constituent and the wetting property of substrate surface, guarantee reliable adhesiving effect between base material and the conductive layer, and can reduce the surface roughness and the square resistance of conducting film; Conductive layer directly forms in the mode of substrate surface by vacuum splashing and plating, has saved and has used optical cement to paste the step of conducting film, provides cost savings; Be coated with hardening coat in the base material front, improve surperficial scratch resistance and chemical resistance, prolonged the useful life of product greatly.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:

3Ratio be 9: 1.
Adopting PETG (PET) film is base material, under the prerequisite of giving the material high light transmittance, provide composite material to be processed into the possibility of different structure, replace hardening coat at the PET back side with RF plasma treatment layer, guaranteeing has reliable adhesion effect between base material and conductive layer, can also reduce the surface roughness and the square resistance of conducting film simultaneously; The transparency conducting layer of this nesa coating uses the mode sputter nano indium tin metal oxide of vacuum splashing and plating, saves the step of pasting conducting film on base material by optical glue, provides cost savings; Coat the scratch resistance that hardening coat can improve product in substrate front side, prolong the useful life of product.The present invention can be widely used in aspects such as contact panel, electronic game machine, childhood teaching machine, smart mobile phone, panel computer.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. the nesa coating of radio frequency plasma, base material is the PET film, it is characterized in that: the front of described PET film scribbles hardening coat, and the hardening coat surface is covered with the PE diaphragm; The back side of described PET film is formed with RF plasma treatment layer, and sputter has transparency conducting layer on the RF plasma treatment layer.
