Hello, I have a quick question regarding an "http://www.sciencenews.org/view/generic/id/38466/title/Blueprint_to_repel_oil_and_water" [Broken] that I just read on ScienceNews regarding hydrophobic surfaces. In the second to last paragraph it's quoted that "although hydrophobic surfaces readily shed water, if they become contaminated with oily substances they lose their water repellency." The confusion I have (and I'm assuming that I'm wrongly inferring from the article) is that I regularly oil my work boots to ensure that they maintain their water repellency. So how does that make sense when oil-contamined surfaces lose their ability to repel water? :uhh: Thanks!
