Abstract

A novel kind of polymer magnetic material iron phthalocyanine (FePc) was prepared via the polymerization of phthalonitrile with iron pentacarbonyl. The pre-polymerization was monitored by FTIR and UV–Vis spectra. Microwave dielectric properties of prepolymers were dependent on their chemical structures. The thermal properties of FePc polymer were evaluated by TGA, the initial decomposition temperature of completely cured polymer was about 420 °C and char yield at 800 °C was 63.56%. Controlling the pre-polymerization degree of phthalonitrile by the reaction time, the magnetic properties of cured polymer materials can be finely tuned. The saturation magnetization of cured polymer decreased from 2.48 to 0.42 emu/g, whereas the coercive force increased from 123.8 to 228.6 Oe. The microstructure of iron phthalocyanine polymer was characterized by scanning electron microscope and the typical layer structure morphology of phthalocyanine polymer was clearly observed.
