摘要
采用一种水溶性聚合物—羟丙基甲基纤维素(HPMC)处理硅溶胶粒子(SiO_2);并以这样的粒子作核,制得了SiO_2/PMMA复合胶囊化粒子;通过电泳实验对其胶囊化效果进行了表征。
A kind of water-solube polymer (hydroxy propyl methyl cellulose, HPMC ) was used to treat sillica sol particles, and SiO2/PMMA composite particles were prepared Via emulsion polymerization in which the HPMC-coated silica sol particles were used as seed. The encapsulation was verified by electrophoresis.
