Introducing a lubricant layer onto surfaces has emerged as a novel strategy to address a wide range of interface-related challenges. Recent studies of lubricant-infused surfaces have extended beyond repelling liquids to manipulating the mobility of fluids. In this study, we report a design of slippery surfaces based on infusing lubricant onto a polyelectrolyte multilayer film whose surface microstructures can be erased rapidly under mild condition. Unlike other lubricant-infused surfaces, the liquid movements (e.g., moving resistance and direction) on such surfaces can be manipulated via programming the surface microstructures beforehand. The work reported here offers a versatile design concept of lubricant-infused surfaces and may turn on new applications of this emerging class of bioinspired materials.
在表面引入润滑剂层已成为解决各种界面相关挑战的一种新策略。最近对注入润滑剂的表面的研究已经超出了排斥液体的范围，而是转向了控制流体的流动性。在这项研究中，我们报告了一种基于将润滑剂注入聚电解质多层膜的设计，该膜的表面微结构可以在温和条件下迅速擦除。与其他注入润滑剂的表面不同，这种表面上的液体运动（例如，移动阻力和方向）可以通过预先编程表面微结构来进行控制。这里报道的工作提供了一种多功能的注入润滑剂表面的设计理念，并可能为这一新兴的仿生材料开辟新的应用。
