摘要

以十二烷基硫酸钠（SDS）和山梨醇脂肪酸酯（Span80）为乳化剂制备了稳定的微水团（MAGs）。Fe3O4/PAM 复合微球（CMPs）是在 MAGs 中进行反乳液聚合得到的。实验结果表明，球形 Fe3O4/PAM CMPs 的尺寸约为 135-420nm，饱和磁化值约为 23.3emu/g。在 Fe3O4/PAM CMP 中，PAM 的质量分数约为 76.5%。含有 Fe3O4/PAM CMPs 的乳液的粘度随电流的增加而增加，随剪切速率的增加而降低。

Preparation of magnetic Fe3O4/PAM composite microspheres by inverse emulsion polymerization

The stable micro-aqueous groups (MAGs) were prepared by using sodium dodecyl sulfate (SDS) and sorbitan fatty acid ester (Span80) as emulsifiers. Fe3O4/PAM composite microspheres (CMPs) were obtained by inverse emulsion polymerization in MAGs. The experimental results showed that the size of the spherical Fe3O4/PAM CMPs was about 135-420nm and the saturation magnetization value of them was about 23.3emu/g. In the Fe3O4/PAM CMPs, the mass fraction of PAM was about 76.5%. The viscosity of the emulsion containing Fe3O4/PAM CMPs increased with the increase of current and decreased with the increase of shear rate
