The electrodeposition of polymer nanocomposite thin fi lms 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 confi rm nanocomposite formation. CV enables electrodeposition of the fi lms. The presence of GO on the PVK-GO surface is confi rmed 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-defi ned fi lm morphology.versatility. This two-dimensional single-atom-thick nanomaterial of hexagonally arrayed sp 2 -bonded carbon atoms exhibits high aspect ratio, outstanding electrical conductivity, mechanical stability, and cost effi ciency. [2][3][4][5][6][7][8][9] With such unique properties and the spectrum of possible applications, graphene has been recognized as one of the most promising nanomaterials. However, just as with the newly discovered allotropes of carbon, the availability and processability have been the rate-determining factors in the evaluation of graphene applications.A major challenge in working with graphene involves achieving homogeneous dispersions for large-scale coating fabrication. For example, in the creation of graphene-organic composites, thin graphitic layers require exfoliated graphite sheets. The non-dispersibility of graphite in aqueous medium and in organic solvents leads to the diffi culty of working directly with graphite. The most common and effective approach is based on the use of graphene oxide (GO) as a precursor. [ 3 , 8-11 ] Compared to its pristine counterpart, GO contains oxygen functional groups (i.e., epoxides, -OH, and -COOH group), [12][13][14] which make it hydrophilic and disperse well even in aqueous solutions. However, aqueous dispersion of graphene is of limited interest because in most of its proposed applications (electronics, sensors, and composites), organic solvents are normally required in the processing
