To fabricate transparent conducting films (TCFs) for electronic devices, both a high conductivity and thermal stability are significant issues due to the need for a high temperature annealing process. In this report, we describe the preparation of a highly transparent (94% transmittance), conductive (surface resistivity: 354 Ω sq−1) and thermally stable double-walled carbon nanotube (DWCNT) film without adding any chemical doping or rinsing. Such film was obtained by a simple dilution and condensation/filtration process (DC/F). The procedure is quite simple, and thus large scalability is easy.
