Vatnshelt efni sem blotnar ekki

Efni sem er búið til með nanótækni og örþunnum strenglum af sílíkoni eru svo vatnsheldir að þó svo að efnisbúturinn væri geymdur í vatni í 2 mánuði þá kæmi það jafn þurt uppúr og það kæmi ofaní.

" "The combination of the hydrophobic surface chemistry and the nanostructure of the coating results in the super-hydrophobic effect," Seeger explained to New Scientist. "The water comes to rest on the top of the nanofilaments like a fakir sitting on a bed of nails," he says."

"The silicone nanofilaments also trap a layer of air between them, to create a permanent air layer. Similar layers - known as plastrons - are used by some insects and spiders to breathe underwater."
