摘要:利用层层自组装的方法制备了粒径和组成可裁剪、具有核-壳式结构的单分散二氧化硅(SiO2)磁球.用X射线衍射(XRD)、透射电镜(TEM)、能谱(EDS)对样品的形貌、组成进行了分析;用电位的变化考察了磁性多层膜在胶体表面的逐步生长.
The fabrication of core-shell monodispersed magnetic silica microspheres with tailored dimensions and compositions was accomplished by layer-by-layer self-assemble. The morphology and compositions of samples were characterized by XRD TEM, EDS. The alternating zeta-potentials were utilized to indicate the stepwise growth of multilayer films on colloids.
