In this study, we have used graphene oxide (GO) and clay in casting PVA films. Our study shows addition of small amount of GO with nanoclay significantly enhances mechanical properties of PVA hybrid nanocomposite. Scanning electron microscopy (SEM) and energy dispersive Xray (EDX) imaging showed that montmorillonite and graphene oxide layers had been in the polymeric matrix. There was a significant improvement in mechanical properties of the films, showing up to 600% increase in tensile strength and 700% in the modulus for a film with montmorillonite and GO, compared to the PVA film
