Synthesis of Raspberry-Like SiO2/Polystyrene Nanocomposite Particles via Miniemulsion Polymerization
Raspberry-like silica/polystyrene nanocomposite particles, silica particle as core and polystyrene nodules as shell, were synthesized through miniemulsion polymerization by using sodium dodecyl sulfate surfactant, hexadecane costabilizer in the presence of silica particles modified by methacryloxy(propyl)trimethoxysilane (MAPTMS) or n-octadecyltrimethoxysilane (ODMS). In this unique process, it was found that the raspberry-like silica/polystyrene nanocomposite particles could be obtained based on MAPTMS grafted silica particles at high grafted density 6.7 μmol/m2. And such nanocomposite particles could possess bigger shape stability due to coordinate effect of both the polymerizable group and hydrophobic interaction provided by MAPTMS molecules. Formation mechanism of the morphology was discussed.
