In this study, we synthesized poly (vinyl alcohol) (PVA) functionalized graphene oxide (f-G) by esterification reaction and used this f-G to stabilize the dispersion of graphene in water. Finally, we used the f-G stabilized graphene to prepare PVA nanocomposite. The results showed that PVA was successfully covalently attached to graphene oxide and the synthesized f-G was able to disperse graphene and form stable aqueous graphene dispersion. With the assistance of f-G, graphene was able to homogeneously incorporate into PVA matrix without destroying the crystal structure of PVA.
