Oleophobic Surfaces - Anti-Graffiti Demo is a hands on cart demonstration for spontaneous, 3-10 minute interactions with visitors. The visitors will explore several surfaces that display oleophobic properties due to material science research at the nano scale. Coatings can preserve, protect, lubricate, grip, and a myriad of other behaviors. For example, walls can be coated with material that when dry, will prevent the adhesion of paint or ink. In this demonstration, we're examining coatings that are oleophobic, "oil hating," and prevent low surface tension liquids from adhering to it.
“Nano sand” is a product that was originally invented to help clean up oil spills in water. Since the “nano sand” is hydrophobic, it does not let water molecules pass through. It does, however, let oil molecules pass through. When oil-contaminated water is exposed to “magic sand”, the oil passes through and leaves clean water behind. And when “magic sand” is sprinkled on top of oil spills, the sand binds with the oil and creates oil- filled sand clumps that fall to the bottom of an ocean or lake.
