Dewetting and anti-icing performance is simultaneously achieved in a structural coating comprising multiple layers, with each layer including (a) a continuous matrix; (b) porous voids, dispersed within the matrix, to inhibit wetting of water; and (c) nanoparticles, on pore surfaces, that inhibit heterogeneous nucleation of water. These structural coatings utilize low-cost and lightweight materials that can be rapidly sprayed over large areas. If the surface is damaged during use, fresh material will expose a coating surface that is identical to that which was removed, for extended lifetime.

Abstract: Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.
Abstract: A sizing composition includes a texturing agent, a film-forming agent, and organic particles dispersed therein. A glass fiber strand is formed from a plurality of individual glass fibers coated with the sizing composition. A thermoplastic composite material includes such glass fiber strands.
