Recently there is a high attempts to investigate the possibility of protecting human body from microwave radiation and electronics packaging. In this study an electromagnetic radiation shielding film by reflecting and/or absorbing the incident wave were prepared as a promising solution. Basically PVC and iron oxide nanoparticles were synthesized using solution casting method to make the protection film. Analysis via VNA has been conducted to understand the shielding behaviour during the exposure to the radiation. The prepared films exhibit ability of absorbing microwave radiation in the range of 8 GHz - 11 GHz, with a maximum value of -10 dB at 30 wt. % of iron oxide nanoparticle. Furthermore microwave absorption performance can be improved by putting two layers or more in order to increase the thickness of the shield. It is suggested that the results are mainly attributable to good effective properties of iron oxide and their homogeneous dispersion in the PVC matrix, also from the analysis it will propose the optimum solutions for this problem.
