Electroless Silver Plating on the Cotton Fiber Modified with 3-mercaptopropyltriethoxysilane

This paper studies on the characteristics of the electroless silver plating cotton fiber modified with 3-mercaptopropyltriethoxysilane.The effects of each factors on surface resistance and rate of weight gain was tested by the method of orthogonal test. It is concluded that the optimal technology for preparing the silver plating cotton fiber:concentration of the 3-mercaptopropyltriethoxysilane 1%, modification time 120min, the bath ratio of modification 1:60,dosage of AgNO3 3.5g, dosage of C6H12O6 3.5g, plating temperature 50℃, plating time 60min. SEM and XRD analysis shows that the silver plating on the cotton fiber modified with mercapto is uniform and density. This fiber has good electromagnetic shielding. The silver coating has excellent adhesion fastness tested by the scotch tape test.
