摘　　要：采用了酸性萃取剂二（2-乙基己基）磷酸（P204）的钠盐作为乳化剂制备了聚苯乙烯-丙烯酸微球。当乳化剂的含量在1．56％-3．54％范围内逐渐增大时，乳液粒子颗粒的直径在300—120nm范围内逐渐减小。以聚苯乙烯-丙烯酸微球为模板制备了ZnS／CdS复合空心微球。所制得的样品采用透射电镜法进行了表征。The sodium salt of cxtractant P2O4 （di - （2 -ethylhexyl phosphoric acid） was used as the emulsifier in the template synthesis. The diameters of the polymer core decreased from 300 nm to 120 um with increasing of the amount of emulsifier. ZnS/ CdS hollow spherical particles have been prepared using core/shell fabrication method with poly - （ styrene - acrylic acid） （PSA） latex particles as template. The products were characterized by TEM respectively.
