This project aims to develop a new mathematical model to predict the pattern formation of a new class of permanent lubricants. Ionic liquids are conductive and do not evaporate, creating a unique opportunity to develop such coatings. These thin films form patterns where the pattern type (patches, stripes or holes) depends on the liquid/surface interaction. Only some patterns result in good lubrication; current limited understanding of the pattern formation process hampers selection of a good lubricant for a chosen material. Current mathematical approaches are computationally expensive and time consuming. The new model expected from this project would provide a cheap, fast and reliable alternative for screening suitable liquid/surface pairs.

该项目旨在开发一种新的数学模型来预测新型永久润滑剂的图案形成。离子液体是导电的，不会蒸发，这为开发这种涂层创造了独特的机会。这些薄膜形成图案，其中图案类型（斑块、条纹或孔）取决于液体/表面相互作用。只有一些图案导致良好的润滑;目前对图案形成过程的有限理解阻碍了为所选材料选择良好的润滑剂。目前的数学方法是计算昂贵和耗时。该项目预期的新模型将为筛选合适的液体/表面对提供廉价、快速和可靠的替代方案。
