US engineers have created the “most waterproof material ever” – inspired by nasturtium leaves and butterfly wings.

Most clothes still need to be washed and or drycleaned… However, you would have no luck trying to clean anything made of this material! US engineers have created the “most waterproof material ever” – inspired by nasturtium leaves and butterfly wings.

The new “super-hydrophobic” surface could keep clothes dry and stop aircraft engines icing over, they say.

The lotus leaf was thought to be the gold standard for staying dry in nature, but now a team from MIT in Boston say they have surpassed it.

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.
