ABSTRACT

Superhydrophobicity is widely observed in nature with the tendency of a natural surface to be characterised by a water-repellent capability. Over the past thirty years, the production of superhydrophobic surfaces on metals and alloys has received growing interest because of its great significance in a wide range of industrial applications, such as water-proofing, anti-corrosion, anti-icing, drag reduction, self-cleaning, and phase change heat transfer enhancement. This paper presents a comprehensive review of the recent advances in the preparation of superhydrophobic surfaces on metals and alloys, largely focused on copper, aluminium, zinc, and related alloys. It starts with an introduction of the basic principle of superhydrophobicity and surface wettability characteristics. The fabrication methods, chemical and physical properties, advantages, and prospects are summarised and compared. Some promising and innovative applications of superhydrophobic metal/alloy surfaces are also briefly introduced. Finally, challenges affecting the development and application of superhydrophobic metal/alloy surfaces are outlined.

摘要

在自然界中广泛观察到超疏水性，其具有以疏水性为特征的自然表面的趋势。在过去的三十年中，金属和合金上超疏水表面的生产引起了人们的兴趣，因为它在广泛的工业应用中具有重要意义，例如防水，防腐蚀，防结冰，减阻，自-清洁和相变传热的增强。本文全面综述了金属和合金上超疏水表面制备的最新进展，这些研究主要集中在铜，铝，锌和相关合金上。首先介绍了超疏水性和表面润湿性的基本原理。制造方法，化学和物理性质，优点，并对前景进行了总结和比较。还简要介绍了超疏水金属/合金表面的一些有前途的创新应用。最后，概述了影响超疏水金属/合金表面的开发和应用的挑战。
