摘　　要：以纳米氧化铬(Cr2O3)为原料,采用氨气氮化法制备了纳米氮化铬(CrN)粉体。通过原位聚合的方法,在冰水浴中制得CrN/聚苯胺(PANI)纳米复合材料。纳米CrN掺杂的聚苯胺电导率较聚苯胺提高了一个数量级,较文献报道TiN/PANI高一个数量级。Nano-sized CrN powder is prepared by the direct nitridation method from nano Cr2O3 powder, and polyaniline （PANI）/CrN nanocomposite with core-shell structure is prepared by in-situ chemical polymerization in ice bath, then characterized. The conductivity of the PANI/CrN nanocomposite doubles compared to that of pure PANI and PANI/TiN nanocomposite reported in documents.
