The overflow behavior of liquid at a curved surface or a surface border is a common phenomenon in many circumstances of daily life and industry. Accurate control of overflow is beneficial for improving the convenience of our daily life and efficiency of production, thus has great importance not only for enhancing existing applications but for creating new products. The effect of surface wettability on overflow has not been paid enough attention in the past, however, as the development of construction techniques, especially 3D printing, of superwettable surfaces and the understanding of the dynamic interfacial wetting properties, the potential of surface wettability and structure on the overflow control has gained great recognition in the recent decade. On this basis, the feature article will outline the understanding evolution of the overflow phenomenon, and summarise the current research on the control of overflow behavior from aspects including the bioinspired idea, the fabrication of superwettable surfaces, the development of control techniques, the exploration of control mechanisms, , and provide an outlook for the accurate control of overflow by surfactant and additives, along with challenges and perspectives.
曲面或边界处的液体溢出行为是日常生活和工业中许多情况下的常见现象。准确控制溢出对于提高我们日常生活的便利性和生产效率非常重要，因此不仅对于增强现有应用具有重要意义，而且对于创造新产品也具有重要意义。然而，过去人们对表面润湿性对溢出的影响重视不够，随着超润湿性表面的构建技术，特别是 3D 打印技术的发展，以及对动态界面润湿性特性的理解，表面润湿性和结构在溢控方面的潜力在最近十年得到了广泛认可。在此基础上，本文将概述对溢出现象的认识演变，并从仿生思想、超润湿性表面的制备、控制技术的发展、控制机制的探索等方面总结目前对溢出行为控制的研究进展，展望表面活性剂和添加剂对溢控的精确控制，以及挑战和展望。
