Abstract
A new kind of organic prepolymer containing cobalt phthalocyanine ring (Co-FOM) was prepared by reaction from ferrocenyl organic magnetic prepolymer (FOM) and cobalt chloride. The structure of Co-FOM was characterized by Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectrophotometry (UV-vis). The magnetic properties of Co-FOM exhibited stronger magnetism than FOM at room temperature. The maximum saturation magnetization of Co-FOM reached to 15.8 emu/g at the magnetic field of 5000 Oe. Meanwhile, Co-FOM had one resonance peak for dielectric loss and two resonance peaks for magnetic loss in 0.5-18 GHz. Furthermore, this kind of magnetic material had a strong reflection loss at higher frequency (around 17 GHz). So Co-FOM will have potential application in electromagnetic shielding area.
