摘要: 用X射线衍射方法研究了酚醛树脂及对甲基酚醛树脂热解产物本征态及碘掺杂结构,结果表明,不加ZnCl2的酚醛树酯热解产物具有多晶结构,且随Tp升高层间距如值逐渐减小,加入一定比例ZnCl2起着增大比表面积和孔径的作用,掺杂碘后如值比本征态有所增加,对甲基酚醛树脂热解产物虽具有无定形结构,但如值基本上不随Tp变化。

Abstract: X-ray diffraction method has been used to study pristine and doped polyacenic semiconduc-tive materials prepared by pyroiytic treatment of phenol-formaldehyde (PF) and paracresol-formalde-hyde (PCF) resins. The results show that pyroiytic products of PFdisplay a polycrystalline structure and the interlayer distance is shortened with increasing TP. The pristine samples obtined by pyrolysis of PFresin containing ZnCl2in advance are amorphous, ZnCl2plays a role of porous structure formation , increasing specific surface area and the values of dcin all iodine-doped samples are increased in comparison with those of the pristine samples. The pristine samples obtained by pyrolysis of PCF resin show also amorphous structure but the value of dcdoes not change significantly.
