Abstract

In this paper, we proposed novel ideas to synthesize Fe3O4/PAM composite nanoparticles ( Fe3O4/PAM CNPs Taken each water-drop in W/O emulsion system as a mini-reactor and based on the coprecipitation and inverse emulsion polymerization, we obtained magnetic composite nanoparticles using cheap raw materials and simple working procedure. At the same time, compound emulsifiers were used to improve the stability of W/O emulsion system. Fe3O4/PAM CNPs were quasi-sphere with the size range of 70-600 nm around and exhibited superparamagnetic character at room temperature. The saturation magnetization value of Fe3O4/PAM CNPs was 28.9 emu/g..
