  • Patent number: 9396843
    Abstract: The present invention relates to a method of manufacturing a transparent conductive layer and a transparent conductive layer manufactured by the method. The method of manufacturing the transparent conductive layer includes: a) a step of forming a conductive nanowire layer on a base material; b) a step of thermally treating the conductive nanowire layer; c) a step of applying a conductive metal ink on the conductive nanowire layer; and d) a step of thermally treating the base material coated with the conductive metal ink to electrically bridge the conductive nanowires with each other by conductive metal particles of the conductive metal ink.

  • Patent number: 9269478
    Abstract: Provided are a method for preparing a transparent conductive layer and a transparent conductive layer prepared by the method. The method for preparing a transparent conductive layer includes: 1) forming a cellulose derivative film by coating a transparent substrate with a cellulose derivative coating liquid; 2) hydrolyzing the cellulose derivatives by treating the cellulose derivative film using an alkaline agent; 3) forming a metal film by coating the hydrolyzed cellulose derivative film with an organic metal ink and reducing metals on the cellulose derivative; and 4) forming a conductive metal layer by heat-treating the cellulose derivative film with the metal film formed, and a transparent conductive layer prepared by the method. According to the present invention, a process can be simplified, and also a transparent conductive layer having excellent conductivity, transmittance, bending resistance, and low haze can be prepared.
