采用不经活化处理步骤的无活化化学镀方法制备镀银涤纶纤维,分别用X射线衍射(XRD)、扫描电镜(SEM)及傅里叶红外光谱(FT-IR)对纤维镀层及成分进行表征分析。探讨了化学反应的可能机理并测试了镀银纤维的导电性能。结果表明,无活化预处理的化学镀方法适用于涤纶纤维化学镀银,能够快速催化化学镀银反应;通过测试分析,发现制得镀银导电纤维的表面形成了一层致密均匀的金属银层,使得纤维具有良好的导电性能。
The silver-coated polyester fibers were prepared by non-activated electroless plating without activation treatment. The fiber coatings and their compositions were characterized by XRD, SEM and FT-IR. analysis. The possible mechanism of chemical reaction was discussed and the conductivity of silver-plated fibers was tested. The results show that the electroless plating without activating pretreatment is suitable for the chemical silver plating of polyester fiber and can rapidly catalyze the chemical silver plating reaction. Through the test and analysis, it is found that the surface of the silver-plated conductive fiber is formed with a dense and uniform metallic silver layer , So that the fiber has good electrical conductivity.
