Abstract
The study reports some novel information on both production and characterization for the poly [DVB/Fe3O4] composite film deposited by free radical polymerization method. The composite film consists of a combination of organic phase and magnetite nanoparticles. The magnetization behavior of the poly [DVB/Fe3O4] composite film was analyzed with both vibrating sample magnetometers (VSM) and a technique of electron spin resonance (ESR). It was found that the ESR study performed at room temperature showed the poly [DVB/Fe3O4] composite film had strong transition of g (eff) similar to 2.5 (254 mT) due to the Fe3+ S-state ions. This g (eff) value indicated that the composite film behavior was near superparamagnetism. The VSM results also supported the ESR results.
