In this study, we prepared silica nanoparticles with a crosslinked shell layer by a surface-initiated polymerization technique. We synthesized two types of initiators, N-(3,4-dihydroxyphenethyl)-2-bromo-2-methylpropanamide and 2-bromo-N-(3-(trimethoxysilyl)propyl)-2-methylpropanamide. The initiators were anchored onto the surface of silica nanoparticles, and the initiator-immobilized silica nanoparticles were used as initiators of the polymerization of St/DVB and NIPAAm/MBA to prepare a shell layer of crosslinked organic polymers. |
