用原位聚合法制备了聚吡咯／碳纳米管（ PPy／MWNTs）复合物．采用XRD、TGA、FT－IR、SEM、四探针测试仪和网络分析仪表征了PPy／MWNTs复合物的组成、结构、形貌和电性能．研究了不同制备条件，如质子酸及其浓度、MWNTs的质量分数（ωMWNTs ）、引发剂和单体的物质的量比（ nAPS／nPy ）和反应时间对PPy／MWNTs复合物电性能的影响．结果表明，当磷酸浓度为0．1 mol／L、nAPS／nPy为1：1、ωMWNTs等于45 wt％、反应时间12 h时，制备的PPy／MWNTs复合物的导电性和介电损耗性能最好．

The PPy/MWNTs composites were prepared by the in-situ polymerization.The composition, struc-tures, morphology and electrical properties of the samples were investigated by XRD, TGA, FT-IR, SEM, four-probe meter and network analyzer.The electrical properties of PPy/MWNTs composites were studied by chan-ging doped proton acids and its concentration,ωMWNTs , nAPS/nPy and reaction time.The results indicate that the PPy/MWNTs composites obtained in the condition of 0.1 mol/L phosphoric acid,ωMWNTs =45 wt%and nPy/nAPS=1:1 for 12 h have the best performances of electrical conductivity and dielectric loss performance.
