Bifunctional 3‐((4‐hydroxybutoxy)dimethylsilyl)propyl methacrylate ( CD ) containing a double bond and a hydroxyl group was synthesized through a coupling reaction of 1,4‐butanediol and (3‐methacryloxypropyl)dimethylchlorosilane. Graphene oxide ( GO ) was functionalized with various amounts of CD through its carboxyl functional groups. Then, grafting through ATRP of styrene was carried out with various proportions of edge‐functionalized GO to evaluate the effect of graphene loading and graft density on nanocomposite properties.
