Chinese scientists have developed a new way to fabricate polymeric vesicles with well-defined PMMA brushes using silica particles as templates by surface-initiated photopolymerization (SIPP).
A cross-linked layer of PDMAEMA was immobilised on the surface of silica particles before photo-initiated polymerisation of methyl methacrylate in the presence of thioxanthone generated PMMA brushes on the vesicles. Removal of the silica cores yielded polymeric vesicles with well-defined PMMA brushes. This robust approach shows great potential for the fabrication and modification of polymer vesicles with differerent sizes and functions.
