采用原位聚合法制备碳纳米管/聚苯胺复合物，并通过透射电镜(TEM)、红外光谱(FT-IR)、热重分析(TGA)对样品进行表征，用矢量网络分析仪系统检测了一系列复合物的电磁参数，计算并分析了聚合时间、聚合温度、盐酸浓度、涂层厚度等工艺条件对复合物吸波性能的影响.结果表明，原位聚合法制得了具有核-壳结构的复合物；且聚合时间为6h、聚合温度为20℃、盐酸浓度为0．05 mol/L 时，复合物在8~18 GHz频率范围内具有较好的微波吸收性能.

Carbon nanotubes/PANI composites were prepared by the in-situ polymerization.The morphology, constitution and thermal stability of the products were characterized by TEM,FT-IR and TGA respectively.The electromagnetism parameters of the composites were investigated by vector network analyzer.On the basis of the parameters,the influence of polymerization time,polymerization temperature,acid concentration and coat-ing thickness on the microwave absorbing properties were evaluated.Results show that the core-shell structure composites are obtained.When the polymerization time was 6 h,the polymerization temperature was 20 ℃ and the acid concentration was 0.05 mol/L respectively,the samples have good microwave absorbing properties in the frequency range from 8 to 18 GHz.
