摘要：
Fe3O4/C composites were prepared by using Fe and polyacrylonitrile (PAN) as precursors, and then heat-treated at temperatures of 600,700 and 800 degrees C, respectively. The phase composition of the composites at different temperatures was analyzed by X-ray diffraction, and Fe reacted with O from PAN to form Fe3O4, which contributed to the improvement of magnetic loss of the carbon matrix. Electromagnetic and microwave absorption properties of the composites were investigated. The results show that the values of real and imaginary part of permittivity were all increased as the temperature increasing, and also the microwave absorption capability was improved.
