| Abstract: | A new one-step method for the synthesis of magnetic polymer nanoparticles has been investigated in the inverse microemulsion. The concentration of Fe(II) was found to have a drastic effect on the stability of the microemulsion (or latex particles!). The magnetic properties of the obtained composite latex particles prepared at different c/c) ratios are measured by Vibrating Sample Magnetometer (VSM) and it is found that the heat treatment can increase the magnetic power and superparamagnetic magnetite. TEM and DLS indicate the magnetic polymer particle has a relatively uniform diameter about 100 nm and the particle size can be controlled by the amount of AOT. This method is simple, easily controlled, and applicable to various hydrophilic monomers. Finally, the prepared magnetic polymer particles are transparent and stable for several months. |
