Method for metallizing flexible PET-base ITO conductive layer and application of method

Abstract

The invention provides a method for metallizing a flexible PET (Poly Ethylene Terephthalate)-base ITO (Indium Tin Oxide) conductive layer and an application of the method, belonging to the technical field of chemical plating and being applicable to the edge conductive wiring of an ITO electrode layer of a flexible touch screen and the metallization of a terminal of the edge conductive wiring. A chemical nickel-plating method comprises the eight major steps of solvent degreasing, basic degreasing, alkaline etching, acid activating, precatalyzing, catalyzing, reducing and chemical nickel plating. The method has excellent selectivity to the conductive face of PET plastics and overcomes the defects that a metal coating cannot be formed selectively on the conductive face of the PET plastics by virtue of traditional chemical nickel-plating; the obtained coating is firmly bonded with a conductive base body of the PET plastics, and has good glossiness, and therefore, the resistance of the conductive face of the PET plastics is greatly reduced and the electric conductivity of the conductive face is greatly improved. The chemical nickel-plating method is rich in raw material source, economic and environment-friendly, and applicable to the edge conductive wiring of the ITO electrode layer (conductive PET plastics) of the flexible touch screen and the metallization of the conductive terminal thereof as well as the metallization of other components containing the conductive PET plastics.

Description

technical field [0001] This item relates to a metallization method and application of a flexible PET substrate ITO conductive layer and belongs to the field of electroless plating technology. Background technique [0002] With the advancement of technology and the improvement of human living standards, portable mobile devices (mobile phones, computers, tablets, etc.) and wearable devices (smart watches, etc.) Bigger and bigger, more and more demanding. As the core components of the above-mentioned devices, ordinary hard touch screens can no longer meet the needs of consumers, and flexible touch screens are gradually entering everyone's field of vision. [0003] Currently, LG, Samsung, and Apple are launching their own flexible touch screens one after another. Compared with the traditional hard touch screen, the flexible touch screen has obvious advantages. It is not only lighter and thinner in size, but also lower in power consumption than the original device, which helps ...

Problems solved by technology

However, due to the different properties of the glass substrate and the PET plastic substrate, the key groups on the surface are greatly different, this method cannot be applied to the metallization of the conductive surface of the conductive PET plastic, and a metal coating with clear traces cannot be obtained on the conductive surface of the conductive PET plastic.
