The composition and structure of the core shell structured nano-composites are analyzed by using natural horse spleen ferritin as materials . The impact of nano-composition α-Fe on the electromagnetic parameters and the electromagnetic loss ,the absorbability of nano-composites-α-Fe as wave-absorber is studied as well .The results show that using natural horse spleen ferritin can prepare the core shell structured nano-composites-α-Fe with equidimensional particle-size and the linear particle-size is less than 12 nm .Theε′andε″raise monotonously and at the same time contribute to the rise of μ′and μ″with the increase of compound-α-Fe . The electromagnetic loss is also raised monotonously with the increase of compound-α-Fe ,with the electric loss as the main loss and the magnetic loss as the second loss .Utilization of the nano-composites-α-Fe as wave-absorber can obtain an ideal absorbent effect within the range of centimeter wave .From all these results ,it is concluded that the nano-composites-α-Fe is a new nano-absorbing material having good performances with good corrosion resistance .
