Rather than roughening a solid substrate, an increasingly popular choice is to use an absorbent polymer as the "porous" material. However, to date the polymer choices have been limited to expensive silicone-based polymers or complex assemblies of polymer multilayers on functionalized surfaces. In this paper, we show that hydrocarbon-based polymer films such as polyethylene can be stably impregnated with chemically compatible vegetable oils, without requiring any surface treatment. These oil-impregnated hydrocarbon-based films exhibit minimal contact angle hysteresis for a wide variety of test products including water, ketchup, and yogurt. Our oil-impregnated films remain slippery even after several weeks of being submerged in ketchup, illustrating their extreme durability. We expect that the simple and cost-effective nature of our slippery hydrocarbon-based films will make them useful for industrial packaging applications.13 pagesapplication/pdfen-USCreative Commons Attribution 4.0 Internationallubricant-infused surfacesslippery surfacestunable transparencydrag reductionviscous-fluidheat-transfercondensationcoatingsPerformancedynamicsArticle - Refereedhttps://doi.org/10.1038/s41598-018-29823-7830076322
