    摘要: 本論文以氮- 異丙基丙烯醯胺
    (N-isopropylacrylamide,NIPAAM)和丙烯酸(acrylic acid,
    AA)的乳膠顆粒,在改變AA/NIPAAM 比例及交聯劑濃度
    粒合成,利用乳膠顆粒的AA 鏈段官能基(-COOH)與鐵離
    Fe3O4 會以in-situ 的方式形成,於是磁性乳膠顆粒形成。
    TEM 圖形下觀察粒徑大小及型態;利用紫外光-可見
    光分光光度計在改變溫度下測量450nm 下的吸收值變
    化,得出LCST 變化;利用紫外光-可見光分光光度計在
    放實驗;利用紫外光-可見光分光光度計在280nm 測試不
    同組別的BSA 濃度,可反推鍵結上的BSA 含量。
    In our study, we discuss the copolymer of NIPAAM
    (N-isopropylacrylamide) and AA (acrylic acid) in different
    ratio of AA/NIPAAM and in different concentration of
    crosslinking agent. We test this copolymer in some
    experiments incluiding TEM, LCST, drug release and
    protein (BSA) bonding.
    Then synthesizing the magnetic hydrogel, we use
    different method to synthesize “iron oxide/polymer” form
    the traditional method. In our work, we firstly synthesize the
    hydrogel. Second, using the functional group(-COOH) on
    the hyrogel surface to bond with Fe2+ and Fe3+. Finally, we
    put ammonia into the latex, and we can get magnetic
    According to each test about poly(NIPAAM-co-AA),
    we choose suitable group to synthesize magnetic hydrogel.
    Then we test all events described in the first paragraph.
    From all testing experiments, we can realize the properties
    of the (magnetic) hydrogel and the effect on experimental
    results from each parameter.
