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 method for preparing a patterned conducting element. The method comprises the steps of providing a substrate; forming a patterned adhesive layer on a surface of the substrate; forming a carbon nano tube layer on the surface of the patterned adhesive layer; solidifying the patterned adhesive layer, and forming a fixed carbon nano tube layer which corresponds to the patterned adhesive layer and an unfixed carbon nano tube layer which does not correspond to the patterned adhesive layer; and removing the unfixed carbon nano tube layer, and forming a patterned carbon nano tube layer.
Description
technical field [0001] The invention relates to a method for preparing 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 durabi...
