摘要
应用正交试验法研究巯基改性棉纤维表面化学镀银的特性,测定各因素对表面方阻和增重率的影响,得出制备化学镀银棉织物的最佳工艺:巯基硅烷浓度1%、改性时间120 min、改性液浴比1∶60、硝酸银用量3.5g、葡萄糖用量45 g、化学镀温度50℃、化学镀时间60 min.SEM和XRD分析表明,巯基改性棉织物镀层均匀致密,具有良好的电磁屏蔽性.采用透明胶带法测试证实,该镀层结合牢固.
The characteristics of the electroless silver plating cotton fiber modified with 3-mercaptopropyltriethoxysilane were studied.The effects of each factors that influence surface resistance and rate of weight gain were tested by the method of orthogonal tests.The optimal conditions for preparing the silver plating cotton fiber were：concentration of the 3-mercaptopropyltriethoxysilane 1%,modification time 120 min,the bath ratio of modification 1∶60,dosage of AgNO3 3.5 g,dosage of C6H12O6 3.5 g,plating temperature 50 ℃,plating time 60 min.SEM and XRD analyses shows that the silver plating layer on the cotton fiber modified with mercapto is uniform and dense.This fiber has good electromagnetic shielding.The silver coating has excellent adhesion fastness tested by the scotch tape test.
