Abstract
In this work, thin films of multi-walled carbon nanotubes (MWCNT) were deposited on glass substrates utilizing the dip coating method, utilizing a surfactant to dissolute the CNT in water, aiming their application as transparent conductive contacts. Different surface preparation and CNT concentrations were tested. The electrical, optical and morphological properties were characterized. The results indicate the formation of a non uniform film with CNT aggregates distributed on the surface. Residual surfactant remains in the films, decreasing the transparency of the film. The DI water rinse stage after deposition removes not only surfactant, but also small portions of CNT thin layers, affecting the conductivity of the films. Better results were obtained for the intermediate CNT concentration tested, however other surfactant should be tested to improve film uniformity and conductivity.
