以工业化的聚苯乙烯中空微球为模板,利用种子乳液法合成了粒径均一的功能化中空聚苯乙烯/聚4-乙烯基吡啶(PS/P4VP)微球,改变制备条件可以控制功能基团4-乙烯基吡啶(4-VP)在聚苯乙烯微球表面的分布。合成的微球在水和有机溶剂如二氯甲烷、乙醇、乙腈等中有良好的分散性,并能促进油水体系混溶。
The hollow polystyrene / poly (4-vinylpyridine) (PS / P4VP) microspheres with uniform size were synthesized by using the industrial polystyrene hollow microspheres as the template. The functional groups Distribution of 4-vinylpyridine (4-VP) on the Surface of Polystyrene Microspheres. Synthetic microspheres in water and organic solvents such as dichloromethane, ethanol, acetonitrile, etc. have good dispersion, and can promote the oil-water system immiscibility.
