摘　　要：利用原位聚合法制备导电聚苯胺和涤纶复合织物,该复合织物经超支化聚酰胺-胺/Ag+络合液活化处理后,采用化学镀方法在其表面均匀沉积金属铜,得到铜/聚苯胺/涤纶复合织物。利用扫描电子显微镜、X射线衍射、电磁屏蔽效能等方法对试样进行测试分析,结果显示,聚苯胺作中间层可使铜层平均粒径明显降低,热稳定性和耐摩擦性等性能有所提高,且在300kHz^3GHz频率范围内铜/聚苯胺/涤纶复合织物的电磁屏蔽效能最高可达130dB。Conductive polyaniline and polyester composite fabric（PANI/PET）is prepared by in-situ polymerization,and after it is activated by hyperbranched polyamidomine/Ag＋,Cu is uniformly deposited on its surface by electroless copper plating,finally Cu/PANI/PET composite fabric is obtained.Scanning electron microscope,X-ray diffraction and electromagnetic shielding effectiveness are used to analyze the samples.The results show that using PANI as the middle layer can reduce the average grain size apparently and improve the thermal stability and the friction resistance,and the electromagnetic shielding effectiveness of Cu/PANI/PET can reach 130 dB in the frequency range of 300kHz-3GHz.
