【Abstract】 The intercalation compound was synthesized by mixed molten salt with carbon fibers as host and CuCl₂ as guest. It is found that the microcrystal in the intercalation compound becomes more when its structure is analyzed by X ray diffraction. The surface morphology, characters of thermal stability and IR extinction of the intercalated carbon fibers are compared with the plated carbon fibers. The results show that both intercalated carbon fibers and copper-plated fibers can interfere infrared from 8 to 14μm, and the average mass extinction coefficient of the latter is slightly more than the former. When the decomposed percentage of the sample is 5%, the temperature of the intercalated carbon fibers is higher than that of the copper-plated, which is 660.6℃ and 545℃, respectively.更多还原
