摘要
以苯乙烯、对苯二乙烯、正硅酸乙酯、正十六烷及γ-甲基丙烯酰氧基丙基三甲氧基硅烷为原料,采用双原位细乳液聚合工艺,以过氧化氢异丙苯-四乙烯五胺为氧化还原引发体系制备了粒径在150 nm左右、含硅质量分数高达63%、规整性较好的树莓状纳米复合微球。研究发现加入聚苯乙烯提高了体系的稳定性;γ-甲基丙烯酰氧基丙基三甲氧基硅烷不仅可作为功能单体参与二氧化硅的改性,同时也可起到增容剂的作用。
Inorganic compound/polymer nanocomposites have drawn a lot of at- tention due to their wide applications in medicine, coating, cosmet- ics, catalysis, biology, and so on. Based on our previous works, raspberry-like silica/polymer hybrid particles have been fabricated successfully via double in situ miniemulsion polymerization.
