摘　　要：通过吡咯(Py)对涤纶织物进行原位聚合,获得具有导电和电磁屏蔽性能的涤纶织物。探究了Py浓度、氧化剂FeCl3质量浓度和原位聚合时间对涤纶织物表面电阻值和电磁波屏蔽效能的影响,并用扫描电子显微镜(SEM)和拉曼光谱(Raman)对原位聚合涤纶织物进行表征。结果表明,涤纶织物的导电性和电磁波屏蔽性能随着Py和FeCl3浓度的提高以及原位聚合时间的延长而提升。Py原位聚合整理涤纶织物的最佳工艺为:Py 0.2 mol/L,FeCl310 g/L,原位聚合时间2 h,制备的涤纶织物表面电阻值低至0.14 kΩ/cm,电磁波屏蔽效能超过75 dB。The polyester fabric with conductive and electromagnetic shielding properties is obtained by in-situ polymerization of pyrrole(Py).The effects of Py concentration,oxidant FeCl3 concentration and in-situ polymerization time on the surface resistance and electromagnetic shielding effectiveness of polyester fabric are investigated,and the polyester fabric is characterized by scanning electron microscope(SEM)and Raman spectroscopy.The results indicate that the conductivity and electromagnetic shielding performance of polyester fabrics increase with the increase of Py and FeCl3 concentrations and the elongation of in-situ polymerization time.The optimal process of in-situ polymerization of polyester fabric is:Py 0.2 mol/L,FeCl310 g/L,polymerization time 2 h,the surface resistance value is as low as 0.14 kΩ/cm,and the electromagnetic shielding efficiency exceeds 75 dB.
