Developing versatile, scalable, and durable coatings that resist the accretion of matters (liquid, vapor, and solid phases) in various operating environments is important to industrial applications, yet has proven challenging. Here, we report a cellular coating that imparts liquid-repellence, vapor-imperviousness, and solid-shedding capabilities without the need for complicated structures and fabrication processes. The key lies in designing basic cells consisting of rigid microshells and releasable nanoseeds, which together serve as a rigid shield and a bridge that chemically bonds with matrix and substrate. The durability and strong resistance to accretion of different matters of our cellular coating are evidenced by strong anti-abrasion, enhanced anti-corrosion against saltwater over 1000 h, and maintaining dry in complicated phase change conditions. The cells can be impregnated into diverse matrixes for facile mass production through scalable spraying. Our strategy provides a generic design blueprint for engineering ultra-durable coatings for a wide range of applications.
开发出在各种操作环境下都能抵抗物质（液相、气相和固相）附着的多功能、可扩展且耐用的涂层对工业应用至关重要，但事实证明这具有挑战性。在此，我们报告一种蜂窝状涂层，它无需复杂结构和制造工艺就能赋予拒液性、防潮性和固体脱落能力。关键在于设计由刚性微壳和可释放纳米籽晶组成的基本单元，它们共同作为刚性屏蔽层以及与基体和基底化学键合的桥梁。我们的蜂窝状涂层具有很强的耐磨性、超过1000小时的增强的耐盐水腐蚀性以及在复杂相变条件下保持干燥，这些都证明了其耐久性和对不同物质附着的强大抵抗力。这些单元可以通过可扩展喷涂浸渍到各种基体中以实现便捷的大规模生产。我们的策略为工程设计用于广泛应用的超耐用涂层提供了通用设计蓝图。
