Microwave Absorption Properties of Nano-Iron Epoxy Resin-Based Composite Material

A novel nano-iron particulate reinforced polymer-based composite material against electromagnetic pollution was prepared for household appliances. The attenuation, permittivity and various absorbing aspects of the composite materials were investigated. Results indicated that the composite materials exhibit promising effects of microwave absorption. The attenuation was affected by volume fraction of nano-iron powders. A single microwave absorption medium won’t be appreciable, and a combination of different microwave absorption materials is suggested.
