| Résumé : |
Nowadays smart polymers, smart materials, smart coatings are getting a lot of attention in the research field. Amongst them smart coatings are the fastest developing and the most interesting technology. Smart coatings are called as "SMART'? because they respond to environmental changes in a predictable and noticeable manner. The technology discussed in this paper is "Superhydrophobic coating". This effect, was originally observed in the nature (e.g. on lotus leaves), and is important fora wide range of scientific and technological applications, like developing coatings that possess self-cleaning properties, prevention of surface fouling and anti-corrosion. Superhydrophobic surfaces are those whose water contact angle is greaterthan 150° and have low surface energy. Water droplets do not slide, but roll down the superhydrophobic surface, carrying dust along with it and thereby cleaning the surface. The corrosion protection mechanism is related, first, to the reduction of the electrolyte—metal contact area, and second, to the reduction of the corrosion current. Such coatings are also used to reduce leakage currents on the surface of silicon insulators .This paperfocuses on superhydrophobic coatings based on silicone resins, fluoro-organiccompounds and nanomaterials. |
