摘　　要：采用原位聚合法,以聚乙二醇-6000(PEG-6000)为表面活性剂合成网状纳米聚吡咯(PPy),并考察了反应物的物质的量比对产品的形貌和吸波性能影响。利用扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)、矢量网络分析仪对其进行表征,结果表明,Py∶HCl∶FeCl3物质的量比为1∶0.5∶2时,聚吡咯的吸波性能最佳,在3430MHz处达到了-38.9dB。The nanostructured network of polypyrrole（PPy） was synthesized via insitu polymerization using PEG-6000 as the surfactant.The effect of molar ratio of reagents on the feature and absorbing properties has been studied deeply.PPy was characterized by scanning electron microscope（SEM）,fourier transform infrared spectroscopy（FT-IR） and vector network analyzer.The results showed that while the molar ratio of Py∶HCl∶FeCl3 was 1∶0.5∶2,PPy had the maximum absorption value of-38.9dB at 3430MHz.
