New anti-reflective coating uses moth eye principle

Новое антибликовое покрытие использует принцип глаз мотыльков For a long time, researchers have been trying to solve the problem of the presence of glare on the screens of computer monitors, televisions and smartphones. However, until now the issue rested on the high cost and low efficiency of the proposed developments. Perhaps scientists from the University of Central Florida found a way out and approached the creation of a technology for the production of highly effective anti-reflective coatings. Scientists took the external structure of the moth’s eye, covered with very small hexagonal protrusions, as the basis for new developments. Passing through a kind of hexagonal nano lens, the light flux is practically not reflected from the surface. Such an eye structure helps moths to see well in the dusk, to fix the danger in time. Scientists followed in the footsteps of nature, but instead of convex lenses, they covered the surface with concave cavities with a diameter of up to 100 nanometers.

As a result of the experiment, a result was obtained that increases the contrast of the image in the sun by 4 times and at dusk – up to 10 times. In addition, there are no prints left on the anti-reflective coating, and the film structure allows it to be used to cover flexible screens. At the moment, it is impossible to accurately determine the start time for using the new technology, work is underway to give the material sufficient wear resistance and strength. Similar developments have already been carried out by various companies. The most significant was the technology introduced by the Oak Ridge National Laboratory (US Department of Energy) – in 2015, a coating that effectively repels water was introduced. Such coatings, in addition to improving image quality on monitors, can also significantly increase the efficiency of solar panels.
