用熔盐法合成了FeCl3膨胀石墨层间化合物(FeCl3-EGICs),并对Ⅰ阶结构的FeCl3-EGICs进行了混合气氛下的还原反应,得到了含有单质铁的膨胀石墨插层复合物Fe-EGIC,其特征层间距为0.587~0.588nm。对还原前后的插层复合物进行了阶结构、热性能、电性能的表征与分析。发现FeCl3-EGIC在空气中具有良好的结构稳定性,及在受热环境中具有较高的热稳定性,并通过电导率测试发现,所制备的插层复合物的电导率较原始石墨有所提高。
The FeCl3-EGICs were synthesized by the molten salt method and the FeCl3-EGICs with the first-order structure were reduced under a mixed atmosphere to obtain an expanded graphite intercalation compound Fe- EGIC, its characteristic layer spacing is 0.587 ~ 0.588nm. The intercalation complexes before and after the reduction of the order structure, thermal properties, electrical properties of the characterization and analysis. It was found that FeCl3-EGIC has good structural stability in the air and high thermal stability in a heated environment. The conductivity of the prepared intercalated composite has been found to be higher than that of the original graphite .
