Preparation of sodium p-styrenesulfonate(cas 2695-37-6)-g-Fe3O4 / SiO2 composite magnetic polymer by ATRP

The Fe3O4 / SiO2 composite particles with superparamagnetism were prepared by co-precipitation method, and the magnetic particles with superparamagnetic iron oxide were prepared by co-precipitation method. The core structure of sodium p-styrenesulfonate(cas 2695-37-6)-g-Fe3O4 / SiO2 composite magnetic polymer was successfully prepared by ATRP. It was proved by FT2IR, EDS, TEM and VSM that the obtained material had both high molecular and magnetic properties, and it was easy to separate the magnetic particles shortcomings of the magnetic particles to improve the chemical stability, and give its surface a variety of reactive functional groups.
