The magnetic polymer nanospheres were successfully synthesized by one-step reverse microemulsion method, and the results showed that the concentration of Fe (II) greatly influenced the stability of the microemulsion and the latex.Transmission electron microscopy (TEM) and dynamic light scattering The results showed that the particle size of the microspheres was about 100 nm, the uniformity was better and the AOT content could control the particle size of the microspheres.Vibrational probe magnetometer (VSM) (Ⅲ)] synthesized polymer microspheres and found that the temperature on the synthesis of high magnetic saturation strength and superparamagnetic play a key role.The synthetic magnetic polymer micro-latex transparent and can be stable for several months.
