제목 Synthesis of poly(oligoethyleneglycol methacrylate) coating TiO2 nanoparticles by surface-initiated ARGET ATRP
초록 Poly(oligoethyleneglycol methacrylate) (POEGMA) covalently attached to TiO2 nanoparticles (NPs) were synthesized by the surface-initiated ARGET ATRP. The growth of polymer chains from the ATRP-initiator functionalized nanoparticles surface was achieved under mild condition by using copper (II) as a catalyst and zerovalent copper (Cu0) or L-ascorbic acid (AsAc) as reducing agents. The as-synthesized nanocomposites were characterized by FT-IR, TGA, FE-SEM and TEM analyses. FT-IR results suggested the formation of polymer chains covalently attached to nanoparticles surface. The TiO2 nanoparticles were found to be imbedded in polymer matrices as revealed by TEM and FE-SEM images. The TGA curves demonstrated that the using of AsAc afforded the faster grafting rate over Cu0.
