摘要
考察了核壳式表面功能化磁性聚苯乙烯纳米微球的可控制备工艺。采用紫外可见吸收光谱、透射电子显微镜、原子力显微镜及在不同溶剂中的分散性实验,对表面羧基化的磁性聚苯乙烯纳米微球的结构与形态进行了表征。结果表明,改变外加晶核Fe2O3纳米颗粒数目,可有效实现磁性聚苯乙烯纳米微球的尺寸可控。
The controllable preparation processes of magnetic polystyrene core/shell nanospheres surface-functioned with carboxy group were investigated. UV-Vis, TEM, AFM and dispersing experiment in different solvents were used to characterize the structures and morphologies of these nanospheres. The results indicate that size of the nanospheres can be controlled by changing the addition amount of crystal core Fe2O3 nanoparticles.
