摘要
以3-(甲基丙烯酰氧)丙基三甲氧基硅烷(MPS)改性的SiO_2实心球充当种子,在相对温和的乙醇/水体系中分散聚合,成功制备具有大的中空腔体和明显偏心结构的SiO_2@PSt杂化微球,有望在药物载体和催化领域获得应用。
SiO2@PSt hybrid microspheres with eccentric-structured morphology were successfully prepared via using SiO2 solid particles modified by 3-(methylpropionyloxy) propyltrimethoxysilane(MPS) as seeds in dispersion polymerization system.The eccentric-structured SiO_2@PSt hybrid particles have potential applications in the catalysis and drug upload because of the large hollow cavity.
