Abstract

See full text

A structured material is provided that includes a substrate and a porous structured polymer layer disposed thereon. The porous structured polymer layer includes a plurality of voids, and has a high hemispherical reflectance a high a hemispherical thermal emittance. The structured material is thus particularly advantageous for cool-roof coatings, enabling surfaces coated by the material to stay cool, even under strong sunlight. The material can be produced via structuring of polymers in a mixture including a solvent and a non-solvent. Sequential evaporation of the solvent and the non-solvent provide a polymer layer with the plurality of voids.
