US Patent 8021747 - Transparent electrode with net-like CNT film

This patent from Samsung teaches another variation of carbon nanotube transparent electrodes for applications in flat panel displays and touch screens. Claim 1 reads:

1. A transparent carbon nanotube (CNT) electrode, comprising:

a transparent substrate; and

a CNT film having a net-shaped structure formed on a surface of the transparent substrate,

wherein the net-shaped CNT film comprises a network of interconnected CNTs surrounding spaces previously occupied by a particulate material having a particle size of 50 nanometers to 10 micrometers.
