Liquid-infused surfaces (or lubricant-infused surfaces) (LIS) are a new class of functional materials introduced in 2011. Their exceptional properties have earned them a place at the forefront of many fields including anti-biofouling, anti-icing, anti-corrosion, drag reduction, droplet manipulation and drop-wise condensation. Integral to their success is the infused lubricant layer which affords them their properties. In this review, we examine the current state of the literature relating to the lubricant layer. We consider the lubricant through all stages in the surface's lifecycle from design, to use, all the way through to depletion and eventual failure. First, we examine trends in lubricant choice and how to choose a lubricant, including environmental and medical considerations. We then look at the different methods used to infuse lubricant into surfaces and how lubricant depletes from the surface. We then report direct and indirect methods to characterise the thickness and distribution of the lubricant layer. Finally, we examine how droplets interact with LIS and the unique properties afforded by the lubricant before providing an outlook into where research centred on understanding the lubricant layer is heading in the new decade.
液体浸润表面（或润滑剂浸润表面）（LIS）是 2011 年引入的一类新型功能材料。它们的特殊性能使它们在许多领域处于前沿地位，包括抗生物污损、抗结冰、抗腐蚀、减阻、液滴操纵和滴状冷凝。浸润润滑剂层是它们具有这些特性的关键。在这篇综述中，我们考察了与润滑剂层相关的文献的现状。我们考虑了润滑剂在表面生命周期的所有阶段的情况，从设计到使用，一直到耗尽和最终失效。首先，我们考察了润滑剂选择的趋势以及如何选择润滑剂，包括环境和医疗方面的考虑。然后，我们研究了将润滑剂注入表面的不同方法以及润滑剂从表面耗尽的情况。然后，我们报告了直接和间接的方法来表征润滑剂层的厚度和分布。最后，我们考察了液滴与 LIS 的相互作用以及润滑剂赋予的独特性质，然后展望了未来十年理解润滑剂层的研究方向。
