Abstract :
FeNi3 nanospheres (NS) with an average diameter of 400 nm were synthesized by a simple low temperature reduction method. FeNi3@C core-shell structured nanocapsules (NC) were then fabricated with a hydrothermal process. The electromagnetic (EM) properties of paraffin matrix composites containing FeNi3 NS and FeNi3@C NC were studied at 2-18 GHz. The effect of dielectric carbon coating on the EM properties and electromagnetic wave absorbing (EMA) performance was directly observed.
