Abstract

A transparent conductive film which is excellent in transparency, electrical conductivity, in-plane uniformity and durability is disclosed, comprising a metal conductive pattern and a transparent conductive material on a transparent film substrate, wherein the transparent conductive material contains a conductive polymer and at least one of a conductive fiber and a conductive metal. A production method thereof is also disclosed.

Claims (8)

1. A transparent conductive film as an electrode comprising a metal conductive pattern provided on a transparent film substrate and further thereon a transparent conductive material layer, wherein the transparent conductive material layer comprises a conductive polymer and at least one of a conductive fiber and a conductive metal, and the metal conductive pattern having a line width of not less than 1 μm and not more than 100 μm.

2. The transparent conductive film as claimed in claim 1 , wherein the conductive metal comprises transparent metal nanoparticles.

3. The transparent conductive film as claimed in claim 1 , wherein the transparent conductive material layer comprises a base metal-modified conductive polymer formed of the conductive polymer and a base metal.

4. The transparent conductive film as claimed in claim 1 , wherein the conductive fiber comprises a metal nano-wire.

5. The transparent conductive film as claimed in claim 1 , wherein the transparent conductive material layer comprises an ionic liquid.

6. The transparent conductive film as claimed in claim 1 , wherein the metal conductive pattern comprises silver.

7. The transparent conductive film as claimed in claim 2 , wherein the transparent metal nanoparticle is selected from the group consisting of gold, platinum, silver, copper, zinc, palladium, rhodium, iridium, ruthenium, nickel, aluminum, tin, lead, carbon and titanium.

8. The transparent conductive film as claimed in claim 4 , wherein the metal of the metal nano-wire is selected from the group consisting of Ag, Cu, Au, Al, Rh, ir, Co, Zn, Ni, In, Fe, Pd, Pt, Sn, and Ti.
