Poly (vinyl alcohol) supported flexible films of graphene oxide and reduced graphene oxide and their structural study

Abstract

Graphite oxide or graphene has emerged as a promising material for researchers and technological world, because of its amazing mechanical property along with its super electrical property. Therefore, this material has being used in numerous potential utility viz, polymer channels, sensors, energy transformation, and vitality stockpiling gadgets. The synthesis and analysis of PVA Poly( vinyl alcohol) supported GO (graphene-oxide) thin films were described in the performed work. Graphene-oxide was obtained via a facile method which based on the modified Hummers reaction scheme. The morphology and physical properties of graphene oxide were analyzed via Fourier transforms infrared (FTIR), images of SEM and Raman spectroscopy. The spectral outcomes of FTIR analysis showed that the graphite flakes were oxidized, the outcome of this process various functional groups generated which are attached on diametrical ends of structure and basal plane such as C-O-C, C-O, COOH, and C-H, respectively on the surfaces of the graphene- oxide. From the study of Raman spectroscopy, the intensity ratio of G band and 2D band reveals that the obtained materials are monolayer. With the help of SEM analysis morphology of the material could be analyses.
