Graphene is a two-dimentional nanocarbon, which is stimulating great curiosity due to its superior mechanical, electrical, thermal and optical properties. Particularly attractive is the availability of bulk quantities of graphene which can be easily processed by chemical exfoliation, yielding graphene oxide (GO). In this study, poly (2-(N, Ndimethylamino) ethyl methacrylate) (PDMAEMA) chains have been grafted from the GO surface via atom transfer radical polymerization (ATRP), yielding a nanocomposite which can be formed polyioncomplex gel in polyanion (PAA) matrix. The GO and prepared film were characterized by FTIR, XRD, Raman, TGA, SEM and mechanical analysis. Moreover, the gel film can be converted from soft gel state into hard plasticization under ambient room temperature.
