Abstract The “glue + particles” approach has presented an excellent idea for promoting the practicability of superamiphiphobic surfaces. However, strong polar materials, such as epoxy and polyurethane, are usually employed as adhesives. The superamphiphobic behavior will be immediately lost when parts of superhydrophobic particles are removed. Thus, a glue with robust self-healing liquid-repellence is desirable, but remains challenging to realize. Herein, a robust, self-healable, superamphiphobic film was fabricated by a liquid-repellent “glue + particles” approach. The coating based on a sol-gel network showed exceptional liquid-repellency to low surface tension liquids including ethanol. The designed coating is based on robust sol-gel network dangling fluoroalkyl chains which integrates the bonding and self-healing mechanisms for providing a longer usage life. It could withstand at least 400 cycles of abrasion under severe stress (45 kPa), strong acid/base solution, hot-liquids and smudge treatment without apparently changing the superamphiphobicity. This novel and effective coating system may be useful for the development of robust protective clothing for various applications.

通过疏液“胶水+颗粒”方法设计和制造坚固、快速自愈、超疏水涂层

摘要 “胶水+颗粒”方法为提高超疏水表面的实用性提供了一个很好的思路。然而，强极性材料，如环氧树脂和聚氨酯，通常用作粘合剂。当部分超疏水粒子被去除时，超疏水行为将立即消失。因此，需要一种具有强大的自修复液体排斥性的胶水，但实现起来仍然具有挑战性。在这里，一种坚固的、可自我修复的、超疏水性薄膜是通过液体排斥的“胶水+颗粒”方法制造的。基于溶胶-凝胶网络的涂层对包括乙醇在内的低表面张力液体显示出优异的液体排斥性。设计的涂层基于坚固的溶胶-凝胶网络悬空氟烷基链，它集成了粘合和自修复机制，可提供更长的使用寿命。它可以在严重应力（45 kPa）、强酸/碱溶液、热液体和污迹处理下承受至少 400 次磨损循环，而不会明显改变超疏水性。这种新颖有效的涂层系统可用于开发适用于各种应用的坚固防护服。
