铝基超疏水表面的制备及其在包装方面的应用进展

在铝基体上构建具有特殊浸润性的超疏水表面，可以赋予其耐腐蚀、防覆冰、润滑减阻等功能，使其具有更大的应用价值和市场前景。制备铝基超疏水表面的方法主要有刻蚀法、阳极氧化法、沉积法、水热法等。化学刻蚀法、阳极氧化法和水热法等操作简单，应用范围广，但在制备过程中用到的强酸强碱等对环境和人体有害；激光刻蚀法等可以控制超疏水表面微观结构的形貌，但使用设备昂贵，难以大范围使用。为拓展超疏水表面的应用领域，开发简便方法制备多级微纳米粗糙结构、使用黏合层加固微观结构、构建自修复超疏水表面是未来的主要研究方向。

Progress in Preparation and Packaging Application ofSuperhydrophobic Aluminum

A superhydrophobic surface with particular wettability built on the aluminium alloy matrix could accomplish the functions of corrosion resistance, anti-icing, lubrication and drag reduction, indicating greater application value with market prospects. The preparation methods of superhydrophobic aluminum surface include chemical etching, anodizing, electrochemical deposition, and hydrothermal process. Chemical etching, anodic oxidation and hydrothermal methods are easy to operate and widely used, but the strong acid, strong base and other substances used in the preparation process are harmful to the environment and human bodies. Laser etching can control the surface microstructure, but it is difficult to be used in a wide range due to the expensive equipment. In order to expand the application field of superhydrophobic surface, the major research direction will be developing a simple method to prepare multistage micro-nano rough structure, using adhesive layer to strengthen microstructure and constructing self-repairing superhydrophobic surface.
