Abstract The superhydrophobic surface was successful fabricated through spin-coating epoxy resin firstly and transferring the dendrite-like structures to aluminum substrate coated with epoxy resin. The combination of organic coating and superhydrophobic surface with dendritic micro-nano structures prevent the permeation of corrosive ions more effectively. The results indicated the fabricated superhydrophobic surfaces possessed a WCA and WSA of nearly 154° and 0°, exhibiting good superhydrophobicity. Besides, the superhydrophobic surface displayed an excellent repellency to acidic or alkaline droplets. The self-cleaning performance of the superhydrophobic surface against fine sand and chalk dust was also proved. Moreover, the anti-corrosion property of superhydrophobic surface has greatly improved due to the dual function of epoxy resin and the air pockets trapped in superhydrophobic surface. This eco-friendly and facile approach provides a novel strategy to prevent metal from corrosion, which will promote the application of superhydrophobic surface in metal protection field.

通过将枝晶状结构转移到铝基板上，环保地制造具有防腐蚀的超疏水表面

摘要 通过旋涂环氧树脂，将枝晶状结构转移到涂有环氧树脂的铝基板上，成功制备了超疏水表面。有机涂层与具有树枝状微纳米结构的超疏水表面相结合，更有效地防止了腐蚀性离子的渗透。结果表明制造的超疏水表面具有接近 154°和 0°的 WCA 和 WSA，表现出良好的超疏水性。此外，超疏水表面对酸性或碱性液滴表现出优异的排斥性。还证明了超疏水表面对细沙和粉笔尘的自清洁性能。而且，由于环氧树脂的双重作用和困在超疏水表面中的气穴，超疏水表面的防腐性能得到了很大的提高。这种环保、简便的方法为防止金属腐蚀提供了一种新的策略，将促进超疏水表面在金属保护领域的应用。
