摘要
对由聚丙烯腈(PAN)热裂解制备的本征态和碘掺杂聚并吡啶(PPyPy)材料进行了X射线衍射研究.分析结果表明,PAN原样具有高度结晶结构;当PAN加入ZnCl2后进行热解时结构发生了变化,层间距dc随裂解温度(TP)的升高而增大.掺杂碘后,dc值比本征态有所增加.
X-ray diffraction studies have been carried out on pristine and iodine-doped Polypyridinopyridinic materials prepared by pyrolytic treatment of polyacrylonitrile (PAN ). The results show raw PAN has a high-crystalline structure; The structure changes when PAN containing ZnCl2 in advance is pyrolized,the interlayer distance dc increases with increasing pyrolysis temperature (Tp). The values of dc in all iodine-doped samples increase comparison with those of the pristine samples.
