| 摘 要： | 用化学共沉淀法制备了F e3O4纳米微粒,并对F e3O4微球表面进行改性,以磁性F e3O4为核,通过苯乙烯和丙烯酸的乳液共聚,制备了粒径均匀、以苯乙烯和丙烯酸共聚物为壳、表面含有一定羧基的磁性高分子纳米复合微球。测定了此微球的形态、结构和粒径,探讨了聚合单体、乳化剂等因素对微球合成的影响。

| Abstract: | The nano-particles of Fe_3O_4 were prepared by a co-precipitation method,then the nano-Fe_3O_4 particles were modified by oleic acid,the modified Fe_3O_4 nano-particles were copolymerized with styrene and acrylic acid to form the magnetic polymer microspheres with carboxyl group.The microspheres were uniform.The microspheres comprised of copolymer of styrene and acrylic acid as shell and magnetic nanoparticles as core.The morphology and structure of the particles were characterized by XRD,IR,TEM.The effects of monomer,linker,emulsifier and pH etc.on the polymer microspheres have been discussed. |
