摘　　要：本文研究了泡沫状聚苯胺/石墨复合物的制备方法和导电性能。首先石墨固体膨胀剂与苯胺进行原位聚合合成出可膨胀的聚苯胺/石墨复合物,然后利用热膨胀技术制备出泡沫状聚苯胺/石墨复合物。实验结果显示在热膨胀过程中石墨固体膨胀剂被膨胀成多孔的膨胀石墨,同时聚苯胺均匀地包覆膨胀石墨形成了类似泡沫状的聚苯胺/石墨复合物。实验结果说明这种复合物不仅具有特殊的形貌,而且还具有较高的导电率。The preparation method and the electric property of spumescent polyaniline/graphite composites were reported in the paper. Firstly the expandable polyaniline/graphite composites were synthesized by graphite solid vesicant and aniline in situ synthesis, and then the spumescent polyaniline/graphite composites were prepared with the heat expansion technology. The experiment results exhibited that the graphite solid vesicant was expanded to porous exfoliated graphite in the process of the heat expansion. Meanwhile, polyaniline covered evenly on the exfoliated graphite to form the spumescent polyaniline/graphite composites. The experiment results explained that the composites not only provided with the especial morphology but also the higher conductivity.
