涤纶织物铜-银双层化学镀研究

Study on Electroless Copper and Silver Plating on PET Fabric

采用化学镀技术,实现了涤纶织物表面铜-银双层化学镀,借助SEM、EDX和TG测试技术对镀层表面形貌、成分和热性能进行了分析,并对化学镀织物电磁波屏蔽性能和拉伸性能进行了测试。结果表明:涤纶织物经过化学镀铜-银后,热起始分解温度有所下降;镀层致密性和金属成分对电磁波屏蔽效能影响显著;化学镀织物拉伸曲线同时具有金属和纤维的拉伸特性,主要受金属镀层厚度的影响。

Electroless copper and silver plating on PET fabric was operated in the lab. The Cu-Ag-coated fabric was investigated by means of SEM, EDX and TG. The electromagnetic shielding performance and tensile properties were also measured, The results show that the decomposition temperature of Cu-Ag-coated fabric is samller than that of PET fabric. The shielding effectiveness （SE） of electroless plating fabric is greatly influenced by the density of metal and its component. The tensile properties of electroless plating fabric are influenced by the thickness of coated metal.
