Optically transparent, highly conductive coating have been a major theme of thin film science efforts for some years. Carbon nanotubes (CNTs) have been considered as one of the key candidate materials for future electronic device application, due to their high electrical conductivity, and mechanical strength. In this work, CNTs are acid treated with nitric acid then the stable dispersion of CNTs in polar solvent such as alcohols, DMF, etc. was achieved by sonication. CNTs thin films are formed from well dispered CNTs solutions using spray coating. SWNTs thin films exhibit a sheet resistance (Rs) of nearby 103 Ω/sq with a transmittance of 80% on the visible light range, which is attributed by excellent dispersion and interaction among CNTs. This present study gives a new strategy to fabricate the transparent conductive CNTs films with CNT/polymer binder solution while the CNTs films were usually formed from layered structures of CNT and polymer binder. |
