US Patent 7378040 - Method of forming transparent conductive CNT film

http://www.freepatentsonline.com/7378040.html

In numerous display and sensor applications the use of transparent electrodes such as ITO or conductive polymers is necessary. However, many of these conductors require additional protective layers which make the formation of external contacts difficult. This patent from Eikos Inc. teaches a method of using carbon nanotubes for transparent electrodes that do not contain such deficiencies. Claim 1 reads:

1. A method of forming a conductive optically transparent coating or film comprising applying to a substrate a layer of carbon nanotubes having an open structure and a separate layer of a applying another layer of material to said carbon nanotube layer that interpenetrates and compresses said carbon nanotubes and increases sheet conductivity across a surface of said conductive film.

This patent from Eikos includes some broad claims to a carbon nanotube resistance sensor. Claim 1 reads:

1. A chemically sensitive resistor comprising: a resistive region comprising carbon nanotubes; and a conducting electrode on a side of the resistive region, wherein the resistor measures a change in resistance of the carbon nanotubes from a known baseline resistance upon exposure to an analyte.

Too bad the examiner missed prior art such as US Patent 6,528,020.
