Abstract:

Based on the requirements of sustainable development and environmental protection, novel waterborne superhydrophobic coatings that use water instead of organic volatile solvents have gradually attracted substantial attention from scientists. However, related problems such as the dispersibility of water-based coatings, the hydrophobic stability of the coating, and the coating performance have also followed. In this work, the progress on the preparation method of waterborne superhydrophobic coatings is introduced.The feasible solutions related to the poor mechanical durability of waterborne superhydrophobic coatings are proposed, such as preparing an integrated composite structure with internal and external consistency, enhancing the interfacial interaction in the coating or designing a self-healing waterborne superhydrophobic coating. In addition, the research progress of waterborne superhydrophobic coatings in the fields of oil-water separation, anti-icing, self-cleaning and so forth in recent years have been described. The large-scale preparation of waterborne superhydrophobic coating, the enhancement of coating mechanical properties and the study of durability will become the main exploration direction in the future. The industrial applications of waterborne superhydrophobic coatings would be broken through by deepening their basic research.

Key words: waterborne superhydrophobic, coating preparation, surface, interface, regulation, mechanical properties

摘要：

基于可持续发展和绿色环保的要求，以水替代有机挥发性溶剂的新型水性超疏水涂层逐渐成为研究热点，但是水性涂料的分散性及涂层的疏水稳定性、涂层性能等相关问题也随之而来。本文介绍了水性超疏水涂层制备方法的发展现状，针对水性超疏水涂层力学耐久性能差的问题提出可行性方案，例如制备内外一致的一体化复合结构，加强涂层内界面相互作用，交联作用或设计自修复水性超疏水涂层等。此外，还对水性超疏水涂层在油水分离、防结冰、自清洁等领域的进展进行阐述，并探讨了水性超疏水涂层的规模化制备、涂层力学性能的强化和耐久性研究将成为主要探索方向，只有夯实水性超疏水涂层的基础研究，工业应用才能突破。
