While the development of mechanically durable and abrasion tolerant superhydrophobicity on a rigid substrates itself remains a highly challenging task, the design of superhydrophobic coatings that can restrict both the tensile and compressive deformations of soft and deformable substrates is unprecedented—and such an approach would be of potential interest in various applied and fundamental contexts. In this communication, a reaction mixture was developed following a simple 1,4-conjugate addition reaction between selected small molecules and appropriate crosslinkers for achieving ‘tolerant and hard’ superhydrophobicity—which is not just capable of surviving under severe conditions—but also restricts both the tensile and compressive deformations of the selected soft substrates. The compressive and tensile moduli of the selected soft substrates increased by 2.2 × 10⁴% and 1.8 × 10⁴%, respectively, after the deposition of the appropriate reaction mixtures. Moreover, the integration of the crosslinkers in the reaction mixture provided a facile basis to resist the physical erosion/rupture of the selected soft substrates under severe abrasive conditions. Thus, a simple and elegant chemical approach not only controlled the mechanical properties of the porous and fibrous soft substrates under ambient conditions—but also provided highly tolerant superhydrophobicity—which likely leads to various outdoor applications.

设计“宽容且坚硬”的超疏水涂层以冻结物理变形

虽然在刚性基材上开发机械耐用且耐磨损的超疏水性本身仍然是一项极具挑战性的任务，但可以限制柔软和可变形基材的拉伸和压缩变形的超疏水涂层的设计是前所未有的——这种方法将是对各种应用和基础环境的潜在兴趣。在这次交流中，在选定的小分子和合适的交联剂之间进行简单的 1,4-共轭加成反应后开发了一种反应混合物，以实现“耐受性和硬性”超疏水性——不仅能够在严酷的条件下生存——而且还限制了两者所选软基材的拉伸和压缩变形。在适当的反应混合物沉积后，分别为⁴ % 和 1.8 × 10 ⁴ %。此外，交联剂在反应混合物中的整合提供了一个容易的基础，以抵抗所选软基材在严重磨损条件下的物理侵蚀/破裂。因此，一种简单而优雅的化学方法不仅可以控制环境条件下多孔和纤维状软基材的机械性能，而且还提供了高度耐受的超疏水性，这可能会导致各种户外应用。
