A graphene/poly (vinyl alcohol) composite hydrogel based on poly (N-methylolacrylamide-methyl acrylate) was prepared. The additon of GO evidently change the network structure and enhance the pH sensitivity of hydrogel. The stucture of hydrogel was characterized by SEM and XRD. Factors influencing the swelling behavior of hydrogel were investigated, such as monomer component and GO. In additon, the reversibility of pH sensitivity of hydrogel was studied as well, which will have a good application in drug release field.
