Magnetic and conductive characters of poly-N-vinylcarbazole-capped magnetite composite films

摘要

@@INTRODUCTION Among different polymeric materials, poly(N-vinylcarbazole) (PVK) is widely used in light-emitting diodes, xerography and in general as an electro-optically active polymer because of its specific photo-physical properties [1]. The chemical and thermal stabilities of PVK, combined with its excellent electrical properties, make it very useful in the electronic devices [2]. In recent years much research attention has been paid to the conducting polymer nanocomposites with one or more magnetic materials so that polymer possesses both electrical as well as magnetic properties. For the absorption of electromagnetic radiations, ferrites are incorporated in the polymers as they possess high magnetization values which make them useful at higher frequencies [3].
