The expanded graphite composites with iron oxides adsorbed were prepared by expanding the mixture of ferrocene and expandable graphite under high temperatures. The main components of iron oxides were Fe2O3, Fe3O4. With the increase of iron oxides contents, the mean conductivity of the composites dropped slowly, however, the magnetization intensity strengthened gradually. Without prejudice to the electric loss absorption of expanded graphite, the magnetic loss absorption of composites was increased. Compared with pure expanded graphite, the 3mm, 8mm wave dynamic attenuation performances of the composite were obviously superior. The 3mm, 8mm wave dynamic attenuation capabilities were strongest, when the weight ratio of ferrocene and expandable graphite was (2--3):5.
