The graphite intercalation compound with easy low temperature exfoliated and high exfoliated volume was prepared by chemical oxidation method using natural graphite flakes, C2H5COOH, FeCl3 and CrO3 as raw materials, according to the mass ratio of 1:2.8:0.3:0.2. The expansion volume of graSubscript textphite intercalation compounds was 320 mL•g-1 at 300°C and achieved biggest 580 mL•g-1 at 700°C. The composition, structure and properties of the graphite intercalation compound were characterized and analyzed by SEM, FTIR, XRD, TG, DSC, VSM techniques. Results showed that the intercalant of graphite sandwich were C2H5COO- and FeCl3.

The graphite intercalation compound with large exfoliated volume was prepared by chemical oxidation method. The experimental parameters on the exfoliated volume were discussed in detail. It was found that the optimum preparing conditions went as follows: the mass ratio of graphite flakes:C2H5COOH:FeCl3:CrO3=1:2.8:0.3:0.2, the reaction temperature and time were 30 °C and 40 minutes, respectively. The exfoliated volume of GIC reached up to 575 mL·g1 in the conditions. The composition, structure and properties of the graphite intercalation compound were characterized and analyzed by SEM, TG, DSC, VSM techniques. The millimeter wave (MMW) attenuation performances of GIC were investigated by MMW radar measurement device. The results showed that the MMW attenuation properties of FeCl3-GIC are batter than H2SO4-GIC because of its magnetic absorption for millimeter wave.
