Problems solved by technology

However, after the ITO layer is continuously bent, the resistance at the bend increases. As a transparent conductive layer, it has the disadvantages of insufficient mechanical and chemical durability, and there is a phenomenon of uneven resistance and a small range of resistance values.
As a result, existing touch screens have disadvantages such as poor durability, low sensitivity, and poor accuracy.
Moreover, as a transparent conductive layer, the ITO layer is usually prepared by processes such as ion beam sputtering or evaporation, so the preparation cost of the ITO layer is relatively high.
The method of patterning the ITO layer is usually laser etching, which not only has high preparation cost, but also has low preparation efficiency.

Abstract

The invention relates to a patterned conducting element. The patterned conducting element specifically comprises a base, an adhesive layer and a patterned carbon nanotube layer, the adhesive layer is arranged on one surface of the base, and the surface of the patterned carbon nanotube layer is partly embedded in the adhesive layer and is partly exposed outside the adhesive layer.

Description

technical field [0001] The invention relates to a patterned conductive element, in particular to a method for preparing a patterned conductive element based on carbon nanotubes. Background technique [0002] Transparent conductive elements, especially patterned conductive elements, are important elements of various electronic devices, such as touch screens, liquid crystal displays, field emission display devices, and the like. [0003] A patterned conductive element in the prior art includes a substrate and a patterned indium tin oxide layer (ITO layer) formed on the surface of the substrate. However, after the ITO layer is continuously bent, the resistance at the bend increases. As a transparent conductive layer, it has the disadvantages of insufficient mechanical and chemical durability, and there is a phenomenon of uneven resistance and a small range of resistance values. . As a result, existing touch screens have disadvantages such as poor durability, low sensitivity, ...
