Lotus plants and the pure white flower they produce have spiritual meaning in some Asian religions. The lotus has also appealed to scientists for its ability to resist water and stay clean. Now, Turkish scientists say they have discovered a low-cost way to make a plastic material that acts like the lotus.

The Turkish group studies the chemical structure of leaves from the plant called the sacred(神圣的)lotus. They wanted to recreate the ability of lotus leaves to resist water.

Water drops normally flatten and spread out when they fall on a surfacE. But the rough surface of lotus leaves prevents this from happening. When water drops hit the surface of the lotus leaf, they stay rounD. As a result, the water drops roll off the leaves. Dirt rolls off with the water. That makes the plant self-cleaning.

The Turkish scientists say water drops form small balls on the new plastic, just as they would on lotus leaves. They believe in the future the water-resistant substance could be added to the outsides of airplanes. This could prevent heavy ice in water, which is a serious danger for airplanes. The substance could be put on ships to help them break through icy waters more easily.

The scientists say the protective covering they created could also be used to keep water off clothing. It could protect antennas (天线) from snow and icE. These can interfere with the operation of radios and other electronic systems. It could even protect traffic signs from weather damagE.
