| 英文摘要 | 刺激响应型复合微球因其独特的优异性能在药物控释，酶固定等多领域具有广泛应用前景而逐渐受到人们的关注，本文主要对刺激响应型复合微球的制备方法做了适当的探究，并且对所得产品进行了表征和应用测试。 本文首先采用Fe3O4、N-异丙基丙烯酰胺(NIPAM)和丙烯酸(AA)制备了具有磁响应、温度响应和pH响应的多重响应复合微球。先用共沉淀法制备了Fe3O4磁性纳米颗粒，并用油酸对其改性。继而以改性后的Fe3O4为种子，制备Fe3O4@P(NIPAM-co-AA)磁性微球。研究结果表明在pH值为10的合成条件下，复合微球的分散性较好；采用疏水性引发剂可相对增加有机，无机相之间的亲和性。通过扫描电镜、红外...; Recently, stimulate-response composite microspheres have been concerned widely because of its unique excellent performance in many fields such as controlled drug delivery and enzyme immobilization. In this thesis, the methods for preparation of stimulate-response composite microspheres were appropriate proposed. The as-prepared products were characterized and their applications were also carefull...; 学位：工程硕士; 院系专业：化学化工学院化学工程与生物工程系_化学工程; 学号：20620091151255 |
