Abstract:
The title core- shell structure nanocomposite particles were prepared by emulsion polymerization with anion ic and nonionic compound surfactant at pH value 8~ 10. The experiments of light transm i-ttance and hydroph ile- lipophilew ere used for detecting the dispersibility o f particles in organic solven.t Themorphology and structure of the hybrid composite particles were characterized by TEM and FT- IR.

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 - 丙烯酸丁酯 - 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, FT- IR表征了复合粒子的形貌和结构。
