US Patent 8076583 - CNT light-transmitting electric conductor

This patent from Sony teaches a variation of transparent electrodes based on carbon nanotubes having an improved affinity with light-transmitting supports. Claim 1 reads:

1. A light-transmitting electric conductor comprising, on a surface of a light-transmitting support:

a conductive material in which a multiplicity of carbon nanolinear structures are accumulated in two dimensions while making partial contact with each other,

wherein said conductive material is a light-transmitting conductive material composed of said carbon nanolinear structures, and direct bonds are formed between said surface of said light-transmitting support and said carbon nanolinear structures making contact with said surface without the carbon nanolinear structures being buried in the light-transmitting support, and between said carbon nanolinear structures making contact with each other.
