preparation example Construction

[0038] Please also see Figure 1 to Figure 5 , the preparation method of above-mentioned transparent conductor 10, comprises the following steps:

[0039] Step S210 , coating a photoresist on the surface of the transparent substrate 1 to form a photoresist layer 4 .

[0040] The transparent substrate 1 is generally in the shape of a sheet. The transparent substrate 1 is an optically transparent material such as glass, polymethyl methacrylate (PMMA) or polyethylene terephthalate (PET). The thickness of the transparent substrate 1 is 50 μm to 700 μm, preferably 50 μm to 300 μm.

[0041] The thickness of the photoresist layer 4 is 1 μm˜10 μm, preferably 2 μm˜5 μm.

[0042] Step S220 , using the mask plate 5 to expose the photoresist layer 4 , and forming a network pattern 6 on the photoresist layer after development.

[0043] The pattern 6 is formed by multiple channels opened in the photoresist layer 4, and the multiple channels are distributed in a network shape. It should...

Embodiment 1

[0058] see Figure 4 , a method for preparing a transparent conductor, specifically comprising the following steps:

[0059] 1), coating a photoresist (4) with a thickness of 5um on the PET surface to form a photoresist layer;

[0060] 2), then utilize the mask plate (5) to expose the photoresist layer;

[0061] 3), develop by developing solution, obtain desired pattern on photoresist layer;

[0062] 4) Fill the conductive liquid into the pattern lines obtained after development by scraping coating technology. The specific steps are as follows: ① Coat the conductive silver ink on the surface of the photoresist to make the silver ink penetrate into the pattern lines; ② Use IR drying system drying the ink to obtain a conductive network (2);

[0063] 5), using glue remover to remove the photoresist (4) remaining on the surface;

[0064] 6) Apply a layer of PMMA UV curable resin (3) on the surface of the conductive network by a wet coating process and cure, and control the hei...

Abstract

Provided are a transparent conductor (10) and a manufacturing method thereof. The transparent conductor (10) comprises a transparent substrate (1), a conductive mesh (2) and an insulating protection layer (3) which are stacked in sequence. The conductive mesh (2) overlays the transparent substrate (1). The surface (32) of the insulating protection layer (3) at one side far away from the transparent substrate (1) is planar. The transparent conductor (10) avoids the use of indium tin oxide; thus the cost of the transparent conductor (10) is low.

Description

technical field [0001] The invention relates to a transparent conductor and a preparation method thereof. Background technique [0002] Capacitive touch screens are more and more favored by the market in recent years because of their high transparency, multi-touch, long life and many other advantages. At present, vacuum evaporation or magnetron sputtering is usually used to plate transparent conductive material indium tin oxide (ITO) on PET or glass substrates to form transparent conductors for application in capacitive touch screens. [0003] However, indium is a rare metal with relatively small reserves in nature and relatively expensive prices, which makes the cost of transparent conductors relatively high. Contents of the invention [0004] Based on this, it is necessary to provide a low-cost transparent conductor and a preparation method thereof. [0005] A transparent conductor, comprising sequentially laminated transparent substrates, conductive mesh and insulatin...
