Graphene oxide and reduced graphene oxide become center of attraction of researchers for last two decades due to its structural and morphological properties which contribute a unique ability to it. By the incorporation of graphene oxide (GO) or reduced graphene oxide (r-GO) into the polymer matrix makes extraordinary change in its general properties to extraordinary properties. The production of GO and r-GO in large scale with cost effecting way is still become challenge. This present work describes the preparation and characterization of GO incorporated Poly vinyl alcohol (PVA) nanocomposite and r-GO incorporated PVA nanocomposite. By following the modified Hummers reaction technique GO and r-GO. Which is cost effective and easier way GO and r-GO of production. The structural properties of GO and r-GO were examined via UV–vis, FTIR, XRD and SEM. The spectral outcomes of FTIR analysis showed the presence of functional groups in GO and r-GO. The comparative study of GO/r-GO of UV spectra is suggesting for π-π* transition on different wavelength. Various SEM images implied for the formation of ultrathin and homogeneously dispersed PVA supported graphene oxide and reduced graphene oxide nanocomposites. The r-GO is obtained by thermal reduction of GO causing a significant decrease in the amount of oxygen containing groups by which r-GO leads the higher specific surface area with less interlayer separation compared to GO.
