磁性高分子复合微球的研究与应用进展

摘要

Preparation of magnetic polymeric microspheres via monomer polymerization methods was reviewed, including soap-free emulsion polymerization, seeded emulsion polymerization, Pickering emulsion polymerization, miniemulsion polymerization, inverse emulsion polymerization, in situ emulsion polymerization, and dispersion polymerization to prepare non-hollow magnetic polymeric microspheres. The fabrication methods of magnetic hollow polymeric microspheres were also introduced. The applications of these materials in the fields of immobilized enzyme, purification of DNA, and carrier of drugs were described. Finally, the future trends of magnetic polymeric microspheres were prospected.%论述了单体聚合法制备磁性高分子复合微球的研究近况,主要介绍了非中空磁性高分子复合微球的无皂乳液聚合、种子乳液聚合、Pickering乳液聚合、细乳液聚合、反相乳液聚合、原位乳液聚合及分散聚合等制备方法及中空微球的设计与制备方法.概述了磁性高分子复合微球在固定化酶、DNA分离提纯、药物载体等方面的应用.最后对磁性高分子复合微球的发展趋势进行了展望.
