The magnetic and electromagnetic wave absorption behavior of a flexible ironnanoparticle reinforced polyurethane nanocomposite is reported. Surface-initiated polymerization SIP method was utilized to fabricate high quality nanocomposites with uniform particle distribution and tunable particle loading up to 65 wt.. The enhancement of coercive force is observed when the nanoparticles are embedded into the polymer matrix Electromagnetic wave absorption performance at a discrete frequency as studied by metal-backed reflection loss indicates that the SIP nanocomposites can save the weight up to 50 compared to the composite counterpart with micron-size particles.
