采用化学镀和电沉积相结合的简单两步法制备了具有微纳分级结构的Cu/Ni多层镀层。利用X射线衍射仪和场发射扫描电镜对Cu/Ni多层膜的结构和形貌进行了分析。结果表明：微纳米Cu/Ni涂层结晶良好，呈海参状结构，Ni纳米锥阵列均匀分布在垂直于Cu锥圆锥面的方向上。静态接触角的测量来研究表面的润湿性。结果表明，Cu/Ni多层膜具有超疏水性，其与测试液（水）的静态接触角为156 °（>150 °）。Cu/Ni多层涂层由于其独特的形状和超疏水性能，具有广泛的应用前景。(C)2011爱思唯尔有限公司版权所有。
Micro-nano hierarchical structured Cu/Ni multilayer coating was prepared by a simple two-step method combined with electroless and electro deposition. Structure and morphology of the as-prepared Cu/Ni multilayer coating were analyzed by X-ray diffractometer and field emission scanning electron microscopy. Results show that micro-nano Cu/Ni coating is well-crystallized and exhibits sea cucumber-like microstructure with Ni nanocone arrays uniformly dispersed perpendicular to the circular conical surface of Cu cone. Static contact angles were measured to investigate the surfaces' wettability. The result reveals that the Cu/Ni multilayer coating is super-hydrophobic, of which the static contact angle with test liquid (water) was 156 degrees(>150 degrees). Due to its super-hydrophobic property and unique shape, Cu/Ni multilayer coating is expected to have extensive practical applications. (C) 2011 Elsevier B.V. All rights reserved.
