First Claim
1. A touch panel subassembly, comprising:
- a glass substrate;
a first transparent, conductive CNT-based layer provided, directly or indirectly, on the glass substrate;
a deformable foil, the deformable foil being substantially parallel and in spaced apart relation to the glass substrate; and
a second transparent, conductive CNT-based layer provided, directly or indirectly, on the deformable foil, wherein at least one of the first and second CNT-based layers is doped with an n-type and/or p-type dopant.

Abstract
Certain example embodiments of this invention relate to large-area transparent conductive coatings (TCCs) including carbon nanotubes (CNTs) and nanowire composites, and methods of making the same. The σdc/σopt ratio of such thim films may be improved via stable chemical doping and/or alloying of CNT-based films. The doping and/or alloying may be implemented in a large area coating system, e.g., on glass and/or other substrates. In certain example embodiments, a CNT film may be deposited and then doped via chemical functionalization and/or alloyed with silver and/or palladium. Both p-type and n-type dopants may be used in different embodiments of this invention. In certain example embodiments, silver and/or other nanowires may be provided, e.g., to further decrease sheet resistance. Certain example embodiments may provide coatings that approach, meet, or exceed 90% visible transmission and 90 ohms/square target metrics.
