Adding structures to a surface makes it super waterproof
The researchers were able to obtain super-waterproof materials using a novel technique. Water does not penetrate the surface and bounces like a ball in contact with the materials.
So far, impermeability was obtained by coating with certain substances, but now experts in Utah have used another technique.
The method involves the addition of very small structures on the surface of common materials. Thus, any object can become perfect waterproof even airplanes or ships, say researchers.
The new technique was invented by Julie Crockett and Dan Maynes Brigham Young University, who states that the model was a lotus leaf where water is sitting on top of them.
Interestingly, when in contact with a material treated by the new method, the drop does not disperse like normal, the droplets bounce, pictured, rather than roll off.
The researchers were able to obtain super-impermeable objects using different types of structures that were added to the surface.
