Exfoliated graphene oxide (GO) sheets were prepared from natural graphite by a modified Hummer's method, which included oxidative hydrolysis under strong acidic conditions and ultrasonic dispersing. GO was firstly reduced by hydrazine and then followed by a diazonium addition reaction to give graphene containing hydroxyls (G-OH), which was converted to graphene with singel eclectron transfer-living radical polymerization (SET-LRP) initiating groups via esterification with 2-chloropropionyl chloride. Finally, poly(N,N-dimethylacrylamide) (PDMAA) chains were grown from the surface of graphene via in situ SET-LRP to obtain graphene/PDMAA (G-PDMAA) nanocomposite. G-PDMAA nanocomposite showed good dispersity in common organic solvents and aqueous solution.
