摘　　要：采用阴离子表面活性剂十二烷基硫酸钠（ＳＤＳ）处理二氧化钛粒子，然后以这样的粒子为核，用原位聚合方法制得了二氧化钛－聚合物复合胶囊化粒子，探讨了复合粒子形成的条件并推测其形成机理，研究了聚合条件对胶囊化过程的影响。Anionic surfactant sodium dodecylsulfate(SDS) was used to treat titanium dioxide particles, and TiO 2 polymer composite particles were prepared via in situ polymerization in which the SDS absorbed titanium dioxide particles were used as cores. The conditions of forming composite particles were discussed and encapsulation mechanism was suggested. Besides effect of polymerization conditions on encapsulation process was studied.
