Abstract
The electrodeposition of polymer nanocomposite thin films of PVK-GO is demonstrated. Highly exfoliated and stable graphene oxide (GO) solutions are prepared by incorporating poly(N-vinylcarbazole) (PVK) through mixing. Enhanced stability up to 30 d is observed in both aqueous and organic solvents. TGA, XRD, FTIR, and UV-vis measurements confirm nanocomposite formation. CV enables electrodeposition of the films. The presence of GO on the PVK-GO surface is confirmed by the appearance of the C=O and OH stretching vibrations, attributed to the carboxylic and hydroxyl groups of GO. AFM measurements show homogeneous and well-defined film morphology. The electrodeposition of PVK-GO nanocomposite films on conducting substrates is demonstrated by cyclic voltammetry. Solutions of highly dispersed PVK-GO in both aqueous and organic solvents are prepared via noncovalent incorporation of PVK and GO using a solution mixing process. Applications involving transparent electrodes, antistatic films, and non-biofouling surfaces are possible.
