巯基改性PET纤维及化学镀银电磁屏蔽布的研究

Study on the electroless silver plating on mercapto modified PET fiber

采用3-巯丙基三乙氧基硅烷(MPTS)对涤纶纤维表面进行巯基改性,并进行化学镀银.讨论改性处理中巯基硅烷的质量分数、反应时间以及改性液浴比对化学镀银效果的影响,优化的改性工艺:w(MPTS)=1%,120 min,浴比1∶60.改性后织物表面生成了均匀致密的镀银层,得到效果优良的PET镀银导电布,耐摩擦性较好.

Polyester（PET） fabric was modified by 3-mercaptopropyltriethoxysilane（MPTS）,and chemically plated with Ag.The influences of mass fraction of MPTS,the reaction time and the bath ratio of modification solution on the silver plating effect were discussed.The optimal modification process was obtained： w（MPTS）=1%,120 min,the bath ratio of modification 1∶60.The modified PET fabric had uniform and dense silver layer,excellent electroconductive result,and good rubbing resistance.
