Nanotech Material Never Gets Wet, Even When Wet [Nanotechnology]

Through the magic of nanotechnology (we use "magic" only ever so figuratively), chemists from the University of Zurich have developed a new fabric that never gets wet, even after being completely submerged in water for two months.

The fabric is constructed of polyester fibers that are covered in a layer of 40-nanometer-wide silicone nanofilaments. These nanofilaments are spiky and cause water to sit in a sphere above the fabric, a permanent pocket of air protected safely below.

Not only could the fabric create a self-cleaning clothing; it reduces drag in water by 20%. In other words, Michael Phelps could go without washing his bathing suit ever again—a prospect that's probably in mixed demand depending on the specific sexual orientation of the fan. [newscientist]
