STRUCTURAL COATINGS WITH DEWETTING AND ANTI-ICING PROPERTIES, AND COATING PRECURSORS FOR FABRICATING SAME |
摘要 |
Variations of this invention provide durable, impact-resistant structural coatings that have both dewetting and anti-icing properties. The coatings in some embodiments possess a self-similar structure that combines a low-cost matrix with two feature sizes that are tuned to affect the wetting of water and freezing of water on the surface. Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, wherein each layer includes (a) a continuous matrix; (b) discrete templates dispersed that promote surface roughness to inhibit wetting of water; and (c) nanoparticles that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost, lightweight, and environmentally benign materials that can be rapidly sprayed over large areas using convenient coating processes. The presence of multiple layers means that if the surface is damaged during use, freshly exposed surface will expose a coating identical to that which was removed, for extended lifetime. |
