摘要
四氧化三铁聚合物微球因其结合了纳米四氧化三铁的超顺磁性和有机聚合物的多种特殊性质,如生物相容性、刺激响应性、荧光性、良好的分散性等,而在生物、医学、催化、分离等领域有着广泛的应用前景,得到了深入研究。本文按聚合方法分类,综述了利用普通自由基聚合、原子转移自由基聚合(ATRP)、可逆加成断裂链转移聚合(RAFT)、氮氧稳定自由基聚合(NMRP)、活性开环聚合(ROP)等方法在四氧化三铁纳米粒子表面进行接枝聚合制备磁性聚合物微球的研究进展。
Magnetic hybrid nanoparticles have superparamagnetism from magnetite and special properties from polymer parts, such as biocompatibility, stimuli-responsivity, fluorescence, and the dispersion of hybrid nanoparticles, are obviously improved compared to that of magnetite. The research of magnetic hybrid nanoparticles have been intensively pursued because of their potential application in biomedicine, catalysis, separation and other fields. In this paper, the research progress of the preparation of magnetic hybrid nanoparticles via surface-initiated polymerization is reviewed from polymerization mechanism, including traditional radical polymerization, atom transfer radical polymerization （ATRP）, reversible addition-fragmentation chain transfer （RAFT）, nitroxide-mediated radical polymerization （NMRP）, and ring-opening polymerization （ROP）.
