Oil droplets bead on a submerged glass surface. UAlberta researchers developed a way to make the glass repel oil, a discovery that could lead to new technologies for cleaning up oil spills and preventing harm to marine ecosystems.
UAlberta researchers show that a simple glass surface can be made to repel oil underwater. University of Alberta mechanical engineering researchers have shown that a simple glass surface can be made to repel oil underwater. This has huge implications for development of a chemical repellent technology for use in cleaning up oil spills. At the time of spills, marine flora and fauna may come into with the oil, wreaking major damage. Underwater oil-repellent technology can potentially prevent the toxic effect of oil on marine ecosystems. Lead U of A researcher Sushanta Mitra and his team members Prashant Waghmare and Siddhartha Das used surfactants, a key ingredient in soaps and detergents, as a way of making an underwater glass surface repel oil. The researchers propose that making use of this simple principle, large concentrations of surfactant can be added to oil-contaminated water, thereby ensuring that marine plants and animals exhibit similar oil-repellent characteristics and enabling them to overcome the deadly consequences of an oil spill.
