| 摘 要： | 采用改进的乳液聚合法,制备了磁性Fe3O4为核、苯乙烯和丙烯酸的共聚物为壳的磁性高分子复合微球。在透射电镜下观察磁性微球的粒径在130 nm左右;并用FT-IR、XPS和热失重方法表征了复合微球的组成成分、羧基(-COOH)的含量及所含Fe3O4的百分量。结果表明,微球的粒径分布均匀,大小可控,稳定性好,具有一定的抗溶剂性能,可长时间存放,是纳米磁性高分子聚合物网络的雏形。

| Abstract: | Fe3O4/ polystyrene composite microspheres were obtained by improving emulsion polymerization.The modified Fe3O4 nano-particles were copolymerized with styrene and acrylic acid to form the magnetic polymer microspheres with carboxyl group.The morphology and structure of the particles were characterized by FT-IR,TEM,XRD,TG and XPS etc.In this paper,we studied the preparation of the nano-sized,mono-disperse,cross-linked,magnetic composite polymer micro-spheres.There is few literature of the cross-linked,magnet... |
