以正辛烷为模板，将N-异丙基丙烯酰胺引入苯乙烯/γ-甲基丙烯酰氧基丙基三甲氧基硅烷（ KH-570）细乳液共聚体系，制备出温敏型有机-无机杂化纳米微胶囊，再将Fe3 O4磁性纳米粒子在温敏型纳米微胶囊聚合物水溶液中通过原位共沉淀法制备了磁场/温度双重响应性纳米微胶囊。利用红外、透射电镜表征了纳米微胶囊的结构与形貌；采用振动样品磁强计及紫外可见分光光度计对纳米微胶囊的磁场响应性以及纳米胶囊在临界温度附近对甲酚红的载入释放行为进行了表征。结果表明，制备的纳米微胶囊具有核壳结构，平均粒径约为104 nm；该纳米微胶囊具有良好的磁响应性和温度响应性，其磁饱和强度约为1.7 emu/g，最低临界溶解温度在40~50℃。

A thermo-sensitive organic-inorganic hybrid nanocaPsule was synthesized by using octane as temPlate through the introducing of comonomer N-isoProPylacrylamide( NIPAM)to the miniemulsion co-Polymerization of styrene(St)and γ-methacryloxyProPyl trimethoxysilane(KH-570). Magnetic and tem-Perature dual stimuli-resPonsive nanocaPsule was obtained by in situ synthesis of Fe3 O4 nanoParticles in the Presence of the thermo-sensitive nanocaPsule in aqueous solution. The structure and morPhology of nanocaPsules were characterized by FTIR and TEM. The magnetic resPonses of nanocaPsule and the cresol red loading release behavior in the nanocaPsules nearby the lower critical solution temPerature was studied by vibrating samPle magnetometer ultraviolet-sPectroPhotometer. The results show that the resulting nano-caPsule Possessed a core-shell structure,and the average diameter is about 104 nm. The nanocaPsule also exhibit magnetic and temPerature dual stimuli-resPonsive ProPerties. The saturation magnetization of nano-caPsules is 1. 7 emu/g,and the lower critical solution temPerature of nanocaPsules is about 40~50 ℃.
