蕉麻纤维表面化学沉积纳米镍薄膜的形态研究

针对天然植物纤维功能单一及应用领域狭窄问题,通过化学溶液丝光化处理,获得不同形态的蕉麻纤维,再通过纤维表面硅烷接枝处理及常温化学镀等步骤,在蕉麻纤维表面生长纳米镍薄膜。采用扫描电子显微镜对纤维及纳米镍薄膜的表面形貌进行观察分析,结果显示,通过化学镀的方法使蕉麻纤维表面获得了致密的纳米镍薄膜,未处理纤维的表面纳米薄膜比较平整,而丝光化处理的纤维表面的纳米镍薄膜呈现出明显的微凸结构,说明可以通过化学处理蕉麻纤维基体来实现纳米镍薄膜微观形态的调控。

Study of the nickel nanofilm electroless-deposited on the surface of abaca fiber

For the single function and narrow application of natural plant fibers, the abaca fibers with different mor-phologies were obtained by chemical solution mercerized treatment. After the treatments such as surface silanization and chemical plating at room temperature, the nickel nanoparticles were electrolessly deposi-ted on the surface of abaca fiber and related nanofilm was formed. The surface morphologies of the fibers and nano nickel thin film were observed and analyzed by scanning electron microscope. The results show that chemical plating makes the dense nano nickel thin film formed on the abaca fiber surface and sur-face silanization let the nano nickel thin film appear a clear micro convex structure. It is suggested that the morphology of nanometer nickel thin film can be controlled by changing the chemical treatment con-dition for abaca fiber.
