摘　　要：用沉淀法制备了纳米氧化铬(Cr_2O_3)粉体,对纳米Cr_2O_3粉体进行表面改性,使其均匀分散到吡咯单体中,采用原位聚合法制备了纳米Cr_2O_3/聚吡咯(PPy)复合材料。对合成的材料用X射线衍射(XRD)、傅立叶变换红外光谱(FT-IR)和透射电镜(TEM)等方法进行了表征。结果表明:PPy成功包覆在Cr_2O_3表面,形成了纳米Cr_2O_3/PPy复合材料。The nanosized chromium oxide powder was synthesized by precipitation method. The as-synthesized Cr2O3 nano powder was modified to disperse in the pyrrole monomer. The Cr2O/Polypyrrole （PPy） nanocomposite was synthesized by in-situ polymerization method. X-ray powder diffraction, Fourier transform infrared spectroscopy （FTIR） and transmission electron microscopy （TEM） were adopted to characterize the as-synthesized powder. The result indicated that the PPy was coated on the surface of Cr2O3 particles and formed Cr2O3/PPy composite.
