摘要
采用化学镀法在聚酯纤维表面镀覆一层导电银层,采用场发射扫描电镜(FE-SEM)、电子能谱仪(EDS)、X射线衍射仪(XRD)分别对聚酯纤维镀银前后的表面形貌、化学元素组成、银结晶结构进行表征.讨论了乙二胺浓度、Ag NO3浓度、施镀时间和镀液温度对化学镀银聚酯纤维增重率及电阻率的影响,测试化学银镀层与纤维基体的结合牢度和耐腐蚀性.结果表明,最佳工艺条件下,电阻率低至2.31Ω·cm-1;镀层为高纯度的面心立方结构的单质银;银镀层具有良好的与基体的粘结强度和耐化学腐蚀性能.
In our research, a conductive silver layer has been developed on polyester fiber by electroless plat- ing.The surface morphology, elemental composition and crystal structure of polyester fiber before and after silver plating have been characterized by field emission scanning electron microscopy （ FE - SEM ）, energy - disperse spectroscopy（EDS） and X-ray diffraction （XRD）.The effects of the ethylenediamine concentration,AgNO3 con- centration, plating time, and solution temperature on weight gain rate and electrical resistivity of electroless silver plated polyester fiber have been explored.The adhesive strength and corrosion resistance of the electroless silver plated layer have been tested. The results indicate that the electrical resistivity of the fiber can be reduced to 2.31 Ω·cm cm^-1 with optimum process conditions.The layer is of high purity silver with face centered cubic struc- ture.The silver layer has good adhesive strength and corrosion resistance.
