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.
