摘　　要：采用氨解法制备了纳米氮化钛(TiN)粉体,对纳米TiN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TiN/聚吡咯(PPy)纳米复合材料。对合成的复合材料用X射线衍射(XRD)、透射电镜(TEM)、傅立叶变换红外光谱(FT-IR)、四探针测试仪等方法进行了表征与检测。结果表明:PPy成功地包覆在TiN纳米颗粒表面,形成了纳米TiN/PPy复合材料。复合材料具有优良的电性能。Nanosized TiN powder was prepared by the ammonalysis method. The as-prepared TiN nanoparticles were modified to disperse in the pyrrole monomer. The TiN/Polypyrrole （PPy） nanocomposite was synthesized by an in-situ polymerization method. X-ray powder diffraction （XRD）, transmission electron microscopy （TEM）, Fourier transform infrared spectrum （FT-IR） and four-probe measurements were adopted for the characterization of the as-synthesized composite. The results indicated that PPy was coated on the surface of the nano TiN particles and the composite showed good electrical property.
