摘要

導電纖維是智慧紡織品最核心的技術，但仍存在金屬層與纖維附著力不足的問題。本論文嘗試使用常壓電漿（AP-plasma）對耐隆纖維進行表面改質。之後透過浸泡銀銨溶液穩定表面活性，增加之後對金屬的附著力。最後，利用濺鍍銀形成金屬層，成功改善金屬層與纖維附著力，製備一具高耐水性的鍍銀導電纖維。當常壓電漿操作電壓為450W時，耐隆纖維與金屬銀附著力最強；此時纖維可成功耐水洗達30次，線電阻僅144Ω/cm。此外，本製程可使金屬銀滲透至纖維內部，製備皮芯型與分散型複合型態的導電纖維，為智慧型紡織品普及化，提供一兼具耐水洗與導電度的新型導電材料。

The core technology of smart textiles is the conductive fiber. However, there is still a problem that the adhesion between metal layer and fiber surface is insufficient. In this study, the atmospheric-pressure plasma (AP-plasma) treatment was employed to modify the surface of nylon fiber. In addition, the silver ammonium was introduced into nylon surface to enhance the bonding strength after AP-plasma treatment. Then, the silver sputtering was covered on fiber surface to form a silver-coated conductive fiber. The AP-plasma treatment successfully improves the adhesion between metal layer and nylon fiber surface, and enhances the water resistance of conductive fiber. When 450 W of AP-plasma is applied, the adhesion is strongest. At this time, the conductive fiber can be successfully washed up to 30 times, and the line resistance is only 144 Ω/cm. In addition, from the SEM-EDS mapping analysis, the silver atom was successfully penetrated into the nylon fiber. Therefore, a coating and filling composite conductive fiber was achieved. This novel AP-plasma treatment demonstrates an effective approach to prepare a both washable and conductive fiber.
