Graphene-carbon nanotube hybrid transparent conductive films

Abstract

Graphene films grown by chemical vapor deposition of hydrocarbon gases on metal surfaces have been integrated with single-walled carbon nanotube (SWNT) films. Using simple thin film fabrication methods and the sequential deposition of these two components we obtained graphene/SWNT hybrid films with good structural quality. Obtained graphene/SWNT films possess opto-electrical properties better than that of pure graphene or SWNT films, making them promising for transparent conductive film (TCF) applications. The hybrid films have been tested as a transparent electrode in electrochromic (EC) devices to replace indium tin oxide (ITO) TCFs.
