The Superabsorbent Nanosponge That Only Soaks Up Oil (100x Its Own Weight!)

By Sarah Zhang | April 18, 2012 7:37 am

Using carbon nanotubes and a dash of boron, scientists at Rice University have created a sponge that only absorbs oil. The superabsorbent sponge may not be of much use in the kitchen, but selective sucking of oil could be very helpful in cleaning up oil spills in the ocean. Other perks: the nanosponge is attracted to magnets, so that’s they’re easily controlled, and they’re reusable. At the end of this video, grad student Daniel Hashim shows how to extract energy from the oil-soaked nanosponge by burning it. Then you’re left with just the nanosponge, all ready to absorb oil again.

    This is brilliant, and it will have other commercial applications besides cleaning up oil spills. I can’t tell you how many work accidents happen because of oil on the floor that is not adequately soaked up by the existing mats. This technology would not only prevent accidents but also allow the recovery & use of oil that would otherwise be wasted.

    I wonder if this could be useful in a microwave sail. Benford and coworkers used carbon aerogels as very lightweight microwave absorbers that could be levitated by photon pressure; maybe this material could be made even thinner.

    World’s most water resistant jacket anybody? 😀

    Good video

    Waaaaaay better than Corexit.

    Hey Professor! Look what I just dug out of my ear!

    This is incredible, an ingenious development

    Too bad we didn’t have this during the Deepwater Horizon fiasco…but hopefully this material will help clean up the next major oil spill.
