[nanoPost] Nano Polyaniline fibers on surfaces for clean windows

Research Centre USA

The fibers, which are not visible with the naked eye, can dramatically alter the properties of the surface on which they are grown, resulting in many new and exciting applications. The diameters of the tips of the nanofibers can be controlled within a 10nm-40nm range, and the length can be controlled within a 70nm-360nm range.

Using nanofibers, the group developed different kinds of surfaces - some are water-repellent, some attract water, and some even repel oil and dirt. Windows made in this way could stay cleaner for much longer periods of time, as dirt will not stick to them. On the other hand, water attracting surfaces could be used as anti-fog coating (useful for car windshields and windows), seeing as the attraction of the water drops to the surface will cause them to flatten over it uniformly.
