Method for making patterned conductive element
The present disclosure relates to a method for making pattern conductive element. The method includes steps. A substrate having a surface is provide. An adhesive layer is formed on the surface of the substrate. Part of the adhesive layer is solidified to form a solidified adhesive layer and a non-solidified adhesive layer. A carbon nanotube layer is applied on the adhesive layer. The non-solidified adhesive layer is solidified so that the carbon nanotube layer on the non-solidified adhesive layer forms a fixed carbon nanotube layer and the carbon nanotube layer on the solidified adhesive layer forms a non-fixed carbon nanotube layer. The non-fixed carbon nanotube layer is removed and the fixed carbon nanotube layer is remained to form a pattern carbon nanotube layer.
