Surface zwitterionization of graphene oxide (GO) was firstly conducted by grafting poly(sulfobetaine methacrylate) (PSBMA) onto the GO surface via reverse atom transfer radical polymerization (RATRP).

An initiator containing modifier, 4-hydroxybutyl 2-bromopropionate (CBr), was synthesized by the reaction of 1,4-butanediol and alpha-bromoisobutyryl bromide. Subsequently, graphene oxide was functionalized with CBr to yield initiator-anchored graphene (GCBr). Then, GCBr was used as the precursor for ATRP of styrene.
