Carbon nanotubes (CNTs) are high aspect ratio conducting nanocylinders possessing unprecedented mechanical, thermal, optical, and electronic properties. They are ideal building blocks for use in assembling a randomly oriented, highly connected nanoporous network. When this network is deposited on top of a substrate surface as a thin film with a thickness in the range of 10-100 nm, it becomes a transparent conducting film-an ubiquitous material, currently dominated by tin-doped indium oxide (ITO). This article reviews recent progress in CNT transparent conducting films and discusses fundamental properties of CNTs important for the formation of these films, methods for CNT dispersion and assembling CNTs into transparent conducting films, properties of the CNT transparent conducting films, and issues remaining to be solved in order to make these films a commercially viable alternative to ITO. © 2011 Materials Research Society.

Transparent electrodes are a necessary component in many modern devices such as touch screens, LCDs, OLEDs, and solar cells, all of which are growing in demand. Traditionally, this role has been well served by doped metal oxides, the most common of which is indium tin oxide, or ITO. Recently, advances in nano-materials research have opened the door for other transparent conductive materials, each with unique properties. These include CNTs, graphene, metal nanowires, and printable metal grids. This review will explore the materials properties of transparent conductors, covering traditional metal oxides and conductive polymers initially, but with a focus on current developments in nano-material coatings. Electronic, optical, and mechanical properties of each material will be discussed, as well as suitability for various applications. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
