Abstract
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
