Lubricant infused surfaces (LIS) are a recently developed and promising approach to fluid repellency for applications in biology, microfluidics, thermal management, lab-on-a-chip, and beyond. The design of LIS has been explored in past work in terms of surface energies, which need to be determined empirically for each interface in a given system. Here, we developed an approach that predicts a priori whether an arbitrary combination of solid and lubricant will repel a given impinging fluid. This model was validated with experiments performed in our work as well as in literature and was subsequently used to develop a new framework for LIS with distinct design guidelines. Furthermore, insights gained from the model led to the experimental demonstration of LIS using uncoated high-surface-energy solids, thereby eliminating the need for unreliable low-surface-energy coatings and resulting in LIS repelling the lowest surface tension impinging fluid (butane, γ ≈ 13 mN/m) reported to date.

润滑剂注入表面的设计

润滑剂注入表面（LIS）是一种最近开发且很有前途的防液方法，可用于生物学，微流体，热管理，芯片实验室等领域。在过去的工作中，已经根据表面能对LIS的设计进行了探索，需要针对给定系统中的每个界面凭经验确定表面能。在这里，我们开发了一种方法，可以先验地预测固体和润滑剂的任意组合是否会排斥给定的撞击流体。该模型已在我们的工作以及文献中进行了实验验证，随后被用于开发具有独特设计准则的LIS新框架。此外，从模型中获得的见识导致使用未涂覆的高表面能固体对LIS进行了实验验证，
