竹子仍然是现代社会的重要组成部分；然而，由于其亲水性和亲油性，其在某些应用中的使用受到严重限制。在这项工作中，我们提出了一种方法，通过结合氧化锌纳米结构的控制和含氟聚合物沉积，使竹子表面具有超双疏性，同时保持其耐腐蚀性。通过水热法将大尺寸玫瑰状氧化锌纳米花（RZN）种植在竹子表面。沉积氟烷基硅烷 (FAS) 薄膜以降低表面能后，所得表面对水、油甚至某些腐蚀性液体（包括盐溶液以及酸性和碱性溶液）在所有 pH 值下均表现出超双疏性。当在环境条件下储存两个月或在 50 摄氏度下在 pH 1 的盐酸溶液和 pH 14 的氢氧化钠溶液中浸泡 3 小时时，所制备的超双疏竹表面非常耐用，并保持其超疏水性，水接触角 >150 度。 (C) 2014 Elsevier B.V. 保留所有权利。
Bamboo remains a vital component of modern-day society; however, its use is severely limited in certain applications because of its hydrophilic and oleophilic properties. In this work, we present a method to render bamboo surfaces superamphiphobic by combining control of ZnO nanostructures and fluoropolymer deposition while maintaining their corrosion resistance. Large-scale rose-like ZnO nanoflowers (RZN) were planted on the bamboo surface by a hydrothermal method. After fluoroalkylsilane (FAS) film deposition to lower the surface energy, the resulting surface showed superamphiphobicity toward water, oil, and even certain corrosive liquids, including salt solutions and acidic and basic solutions at all pH values. The as-prepared superamphiphobic bamboo surface was durable and maintained its superhydrophobic property with water contact angles >150 degrees when stored under ambient condition for two months or immersed in a hydrochloric acid solution of pH 1 and a sodium hydroxide solution of pH 14 for 3 h at 50 degrees C.
