本征态和碘掺杂聚并吡啶材料的X射线衍射研究

X-Ray Diffraction Studies of Pristine and Iodine-doped Polypyridinopyridine materials

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.
