PA6纳米纤维化学镀铜的研究

Study on electroless copper plating of PA6 nano-fiber

采用静电纺丝制备的聚己内酰胺(PA6)纳米纤维为基材,通过氧气等离子体粗化处理,硫酸铜化学镀处理并对制得的镀铜PA6纳米纤维进行表面测试和导电性分析。结果表明:PA6纳米纤维化学镀铜后,金属铜均匀地覆盖在单根纤维表面,并以纳米级的球形铜颗粒生长。当反应温度为42℃,硫酸铜浓度由10 g/L增加至25 g/L时,PA6纳米表面电阻从831.35Ω/sq降至24.41Ω/sq,具有良好的导电性。

The electrospun polycaprolactam（PA6） nano-fiber was exposed to oxygen plasma roughening treatment and electroless copper plating of copper sulfate. The surface area measurement and electric conductivity analysis were performed for the copper plated PA6 nano-fiber. The results showed that copper uniformly covered the surface of single fiber and grew as spheroidal particles by nanometer when PA6 nano-fiber was subjected for electroless copper plating. The surface resistance of the PA6 nanofiber was decreased to 24.41 Ω/sq from 831.35Ω/sq as the reaction temperature was 42 ℃ and the concentration of copper sulfate was raised from 10 g/L to 25 g/L. The fiber had rather good electric conductivity.
