Journal of Materials Chemistry,
A microemulsion-based route to amorphous metal oxide core polymer shell nanoparticles for iron, titanium, zinc and zirconium is presented. The first step consists of the basic hydrolysis and condensation of metal salts, using FeCl2◊4H2O, TiCl4, ZrO(NO3)2, and ZnBr2 as precursors. The formed particles had diams. between 100 and 640 nm and their surface was modified in a second step with silane coupling agents contg. initiating groups for thermally and photochem. induced free radical as well as atom transfer radical polymns. (ATRP). The thus obtained surface-functionalized inorg. cores were used as multifunctional initiators in grafting from polymns. of Me methacrylate (MMA) and styrene as monomers.
