摘要(Abstract)：

为了进一步优化盐基胶体钯法涤纶织物表面的化学镀银工艺,以盐基胶体钯溶液作为活化敏化液在普通涤纶平纹织物的表面进行化学镀银处理,采用扫描电子显微镜及万用数字表对化学镀银层进行形貌及导电性能的测试表征,着重研究了活化敏化浸渍时间、水洗环境和水洗时间对涤纶织物镀银增重率及导电性能的影响。试验结果表明:盐基胶体钯的活化敏化浸渍时间对化学镀银涤纶织物的性能影响不大;不合适的水洗环境及时间会影响织物表面催化活性中心数目及分布,表面镀银层颗粒生长较大,影响其均匀性及紧密程度,最终影响其增重率及导电性能;当活化敏化水洗环境p H=6,水洗时间为10 s时,其导电性能最佳。
To further optimize the process of electroless silver plating on polyester fabric by means of salt-based colloid palladium treatment process, salt-based colloid palladium electroless plating process was ad-opted to coat silver on the surface of polyester fabric. The surface morphology and the conductivity of silvercoated fabric were measured by Scanning Electron Microscope and Digital Multimeter, respectively. More-over, the influences of sensitization-activations time, washing environment and washing time on the masspercentage gain and conductivity of silver plating fabric were studied emphatically. Results reveal that thesensitization-activations time has little effect on the silver plated polyester fabric. The number and distribu-tion of the catalytic activity center on the surface of the fabric are affected under the improper washing envi-ronment and time, which leading to the larger particle size, poor uniformity and compactness of silver coat-ing, thus reducing its weight increasing rate and conductivity. The optimal conductivity is obtained whenp H value is 6 and the washing time is 10 seconds.
