Preparation and Characterization of SiO₂-PMMA with Different Shell Thickness Using AGET ATRP

Abstract:

Monodispersed SiO2-core/PMMA-shell composite nanospheres have been prepared via activator generated by electron transfer atom transfer radical polymerization (AGET ATRP) mediated by an iron (III) catalyst. By simply adjusting the amount of monomer, the shell thickness of products can easily be tuned. Samples were characterized by FT-IR, TEM, 1H NMR. The results showed that the sphere structure kept unchanging after grafting. FT-IR and 1H NMR measurements show that the polymer was grafted on the silica surface successfully. TEM results for composite nanospheres suggested the core-shell-like structure of the hybrid nanoparticle.
