摘　　要：以阴离子与非离子表面活性剂作为复合表面活性剂，反应过程中控制纳米TiO2乳液的pH值在8～10，采用乳液聚合法制备了以纳米TiO2为核，聚甲基丙烯酸甲酯一丙烯酸丁酯一甲基丙烯酸（P[（MMA—BA）-MAA]）为壳的杂化复合粒子。用透光率和亲水亲油实验来检验复合粒子在有机溶剂中的分散性，并借助于TEM，Fr—IR表征了复合粒子的形貌和结构。The title core - shell structure nano composite particles were prepared by emulsion polymerization with anionic and nonionic compound surfactant at pH value 8 - 10. The experiments of light transmittance and hydrophile - lipophile were used for detecting the dispersibility of particles in organic solvent. The morphology and structure of the hybrid composite particles were characterized by TEM and FT - IR.
