多面体齐聚倍半硅氧烷(Polyhedraloligomericsilsesquioxanes)具有低毒性、强疏水性、良好生物相容性等优势,可应用作为生物材料,并被广泛研究。响应性聚合物在外部刺激下能可逆地改变自身物理化学性质,即使是一些很细微的变化,也能发生巨大的变化。在众多的响应性聚合物中,温度响应性和pH响应性尤其受到研究者的青睐;另外,磁性四氧化三铁纳米粒子的靶向性,稳定性好,无毒等特点,使其在生物靶向材料,药物释放等领域具有广阔的应用前景。与传统的单一响应性聚合物相比,具有多重响应性共聚物已然成为一个重要研究方向。本论文基于这样的研究背景,以温度响应性N-异丙基丙烯酰胺(NIPAM)和...Polyhedral oligomeric silsesquioxanes have the advantages of relatively low inertness and good biocompatibility, and are a kind of biomaterials widely studied. Responsive polymer can switch its physical and chemical properties reversibly and immensely under external stimulus, even the stimulus is imperceptible. In numerous responsive polymers, temperature-responsive and pH-responsive polymer are m...学位:工学硕士院系专业:材料学院_工程硕士(材料工程)学号:2072014115012
