Highly conductive and transparent thin films fabricated with predominantly semiconducting single-walled carbon nanotubes

A predominantly semiconducting single-walled carbon nanotube-based thin conductive film was fabricated on a flexible poly(ethylene terephthalate) substrate. The structural features of the nanotubes and careful experimental scrutinization consistently yielded the films with very low surface resistance (590 Omega sq(-1)) and high transparency (80%). The morphological studies of these films before and after acid treatment revealed the self orientation of nanotubes clustered at favorable centers. (C) 2010 Elsevier Ltd.
