Poor mechanical stability, expensive cost, and complex preparation process still limit the practical application of artificial superhydrophobic surfaces. Improving the chemical durability and mechanical stability of superhydrophobic surfaces is an important research direction to promote its commercial application. Herein, we developed a cost-effective and simple method to produce a durable superhydrophobic surface based on a multi-adhesive strategy. Fluorocarbon resin and hydrophobic silica nanoparticles bring excellent hydrophobicity and low adhesion to the coating. And the introduction of bottom resin and phenolic amine adhesive can not only increase the adhesion between superhydrophobic coating and substrates but also increase the mechanical stability of the coating. Even after severe mechanical damage such as abrasion, rubbing, and scraping, the prepared surface can still maintain excellent superhydrophobicity. At the same time, stable resin and inorganic filler bring more than 99 % anticorrosion efficiency, excellent thermal stability, and chemical stability to the superhydrophobic surface. The outstanding performance of the superhydrophobic surfaces in the field of self-cleaning, anti-icing, and frost protection may attract attention for practical application in the industry. The convenience of surface preparation on various substrates by spraying and brushing methods, and the low cost of manufacturing can also greatly expand the application prospect of the developed superhydrophobic surface.

基于多粘合剂策略的耐用超疏水表面制备研究

机械稳定性差、成本昂贵、制备工艺复杂仍然限制了人工超疏水表面的实际应用。提高超疏水表面的化学耐久性和机械稳定性是促进其商业应用的重要研究方向。在这里,我们开发了一种成本效益高且简单的方法来生产基于多粘合剂策略的耐用超疏水表面。氟碳树脂和疏水性二氧化硅纳米粒子为涂层带来优异的疏水性和低附着力。而底层树脂和酚胺胶的引入,不仅可以增加超疏水涂层与基材的附着力,还可以提高涂层的机械稳定性。即使经过严重的机械损伤,如磨损、摩擦和刮擦,制备的表面仍能保持优异的超疏水性。同时,稳定的树脂和无机填料为超疏水表面带来99%以上的防腐效率、优异的热稳定性和化学稳定性。超疏水表面在自洁、防冰、防冻等领域的突出性能可能会引起行业实际应用的关注。喷涂和刷涂方法在各种基材上进行表面处理的便利性,以及较低的制造成本也可以极大地拓展已开发的超疏水表面的应用前景。对超疏水表面具有优异的热稳定性和化学稳定性。超疏水表面在自洁、防冰、防冻等领域的突出性能可能会引起行业实际应用的关注。喷涂和刷涂方法在各种基材上进行表面处理的便利性,以及较低的制造成本也可以极大地拓展已开发的超疏水表面的应用前景。对超疏水表面具有优异的热稳定性和化学稳定性。超疏水表面在自洁、防冰、防冻等领域的突出性能可能会引起行业实际应用的关注。喷涂和刷涂方法在各种基材上进行表面处理的便利性,以及较低的制造成本也可以极大地拓展已开发的超疏水表面的应用前景。
