New waterproof surface is 'driest ever'
Date published: 25th November 2013
Adding tiny ridges to a silicon surface made water bounce off it 40% faster than the previous "limit".
Similar ridges are found in nature on the wings of the Morpho butterfly and the veins of nasturtium leaves.
By applying these patterns to metals, fabrics and ceramics, the scientists hope to inspire a new generation of moisture-resistant products - from tents to wind turbines.
"We believe these are the most super-hydrophobic surfaces yet," said Prof Kripa Varanasi, whose work is published in Nature journal.
"For years industry has been copying the lotus. They should start thinking about copying butterflies and nasturtiums.
"I'm looking forward to working with the fabrics industry to develop new clothing that stays dry longer. What will be the next Gore-Tex?"To continue reading click here
