【摘要】：提出了一种利用纳秒光纤激光快速制备超疏水铝板表面的方法,对样品表面的接触角和粗糙度进行了测量。烘烤处理激光加工后的样品,得到了一系列具有不同润湿性能的铝板表面,增加激光能量密度可得到超疏水表面。研究结果表明,增加激光能量密度除了能提高铝板表面的粗糙度,还会形成明显的微纳二级结构;空气占铝板超疏水复合接触面总面积的90%以上;纳秒激光诱导铝板超疏水表面是微纳结构和化学成分共同作用的结果。
[Abstract]:A method for rapid preparation of superhydrophobic aluminum plate surface using nanosecond fiber laser was proposed. The contact angle and roughness of the surface of the sample were measured.A series of aluminum plate surfaces with different wetting properties were obtained by baking the samples processed by laser, and superhydrophobic surfaces were obtained by increasing the laser energy density.The results show that the increase of laser energy density can not only improve the surface roughness of aluminum plate, but also form an obvious micro-nano secondary structure, and the air accounts for more than 90% of the total area of superhydrophobic composite contact surface of aluminum plate.Nanosecond laser induced superhydrophobic surface of aluminum plate is the result of the interaction of micro-nano structure and chemical composition.
