The removal of liquids, or dewetting, from rough, heterogeneous and structured solid surfaces is central to many engineering and industrial processes, from oil spill cleanup to the cleaning of fabrics and surfaces at home. To date, the majority of studies on dewetting have been limited to binary fluid systems: a droplet removal in the presence of a surrounding bath of gas or liquid. In contrast, this project is concerned with achieving dewetting in ternary-fluid systems, where the droplet is simultaneously interacting with several fluid phases. The project's overarching motivation is to investigate whether such a process can lead to wettability alteration that is more local and can be employed in resource-constrained environments (limited water, polymers and surfactants).

从粗糙，异质和结构化的固体表面中除去液体或脱水是许多工程和工业工艺的核心，从溢油清理到在家中清洁织物和表面。迄今为止，大多数关于脱水的研究仅限于二元流体系统：在存在周围气体或液体浴场的情况下去除液滴。相比之下，该项目与在三元流体系统中实现脱水有关，在该系统中，液滴正在与几个流体阶段同时相互作用。该项目的首要动机是调查这种过程是否可以导致更本地化的润湿性改变，并且可以用于资源约束环境（有限的水，聚合物和表面活性剂）。
