It may surprise you to learn that many brightly colored animals colors They do not have that coloration, but they produce them reflecting light. On this property of Nature is based the lightest paint in the worldwhich can paint a door on both sideswith only a paint fingernail.
Surely you have noticed that the colors of the peacock’s feathers, like that of some ducks or butterflies, They change depending on whether or not the light hits them.. That’s because they don’t use a pigmentation to show the color, but the reflection of light on their feathers or wings.
as it counts techspotscientists of the university of central florida they were trying to make an aluminum mirror using an electron beam evaporator. Things were not going well, and the successive failures had caused a series of nanoparticles aluminum microscopes in the mirror.
They then realized that the ambient light caused these nanoparticles to oscillate, eventually reflecting a single color. By changing the dimensions of these aluminum particlesthey got different colors.
The lightest paint in the world
They created nanoparticles of different sizes, and dissolved them into powder. Then they mixed them with colored materials and binders, to obtain paint.
But it is not an ordinary painting. Is the finest painting in the world. A grain of rice paints a chair for you.
In addition to save moneyhas very important applications in fields such as aeronautics. For example, all the paint on a Boeing 747 weight 450 kilos. But with this structural painting, it would suffice 1.3 kilos. The plane would weigh 1,000 pounds less, and that would save tens of thousands of dollars a year in fuel.
In addition, sunlight spoils conventional paint. Many planes have to be painted up to 4 times a year. Instead this painting does not spoil with sunlight, so it would last the lifetime of the device.
Unfortunately they can only make it on a small scale in the laboratory. They are already looking for business partners to sell it. sure the lightest paint in the worldit would be a great sales success.
