摘要
Carbon films were fabricated by the carbonization of polyimide composite films with the incorporation of different metal catalyst. The carbonization process and the properties of the carbon films were investigated by X-ray diffraction, scanning electron microscopy, four-point-probe device and vibrating sample magnetometer. It was found that the metal complex in the polyimide films promoted the carbonization of matrix polyimide and resulted in the increase of electrical conductivity of the films. The change from para-magnetic to ferromagnetic behavior was also observed with the increase of carbonization temperature.
