1、（20届）本科毕业设计非钯活化的织物化学镀技术的研究IV摘要：面对日趋恶化的电磁污染，为有效降低电磁辐射的危害，人们采用了许多方法，开发防电磁污染新材料越来越受到人们的重视。化学镀金属织物是一种很好的电磁波屏蔽材料，它兼有金属的导电、电磁波屏蔽特性和织物的柔软、透气等特性。作为一种能够在电磁环境中进行电磁辐射防护的防护载体，已成为纺织的焦点。大多数织物的前处理都采取上述“粗化、敏化、活化”步骤,但是工序繁杂,成本较高。采用非活化钯技术对织物进行化学镀，对人体伤害小,成本低，布面与金属的结合力提高,织物
2、表面电阻降低,织物厚度较薄,各方面的性能优良。本文先对增重率、电阻值、电磁屏蔽性能的相关性研究表明，镀后织物的防辐射性能远优于一般的涤纶织物。然后对镀层织物的透气性、硬挺度、强力性能的相关性研究表明，由于镀层织物的厚度增加，透气性不是很好，但刚柔性、强力综合服用性能优良。最后得出非钯活化镀银织物和化学镀镍织物非活化液的工艺配方。关键词：化学镀；非活化；导电性；电磁屏蔽性；IVResearchonanon-activationprocessforelectrolessplatingAbstract：Fa
