New Nanotech Fabric Never Gets Wet

holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

    Wouldn't it be nasty if the outside were hydrophobic and the inside hydrophylic - your sweat would be yanked into the material and violently ejected from the other side! You'd look like your own Vegas water fountain show as you ran along.

    Reminds me of what the Fremen used to coat their underwater water stores.

    I wonder what new and strange water behavior could be observed in a container lined in this. Would there be a meniscus -- either convex or concave -- when water was put into it? Or would the water huddle nervously in the middle, unsure of what do with itself?

    Or as your name suggests it could be used to line the inside of a desert suit a la dune. Collect the moisture and recycle it.

    Forget the water recycling, Muad'Dave just invented a perpetual motion machine! Although the buttered cat may constitute prior art.

    ...of photo-icons which appear on these stories! Poor Einstein looks like he's going to get seriously injured by a falling motherboard. As far as this cloth goes, I don't see that it is necessarily stated that the it prevents water from permeating, just that the cloth itself doesn't get wet.

  8. Great news for slashdotters by slashnot007 · · Score: 3, Funny

    No more wet beds! Also this will be great news for the British public restroom officials. After years of experimenting with Wax paper as toilet paper they can now go high tech. (Can anyone explain to me why on earth the british public restrooms use velum-like TP?) The downside is that now when you accidentally pee in your trowsers, instead of getting a wet spot it all ends up in your shoe.

    No, actually a place which has lipstick on the glass at your table is a place in which I'd be worried about the hygeine. Also, what was that funny squiggle at the end of your post?

    I believe anyone who gives me a glass with lipstick or any kind of blemish on it should be executed since they obviously do respect me as a human being and therefore cannot be a valuable member of society.~
