Surface-initiated atom transfer radical polymerization from halogen-terminated Si(111) (Si-X, X = Cl, Br) surfaces for the preparation of well-defined polymer-Si hybrids

The halogen-terminated Si(111) (Si-X, X = Cl, Br) surfaces contain effective initiators for surface-initiated atom transfer radical polymerization. Well-defined polymer-Si hybrids, consisting of covalently tethered (Si-C bonded) functional polymer brushes, can be prepared directly from the Si-X surfaces.
