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."

This is how Gore-Tex works. You can actually sit on water and it will not come thru the membrane, but water vapor passes thru.
