Abstract: A method is disclosed for producing photocatalytic coated ceramic granules. The method involves providing a coatable composition containing an inorganic binder and a variety of photocatalytic particles, such as TiO2, ZnO, Ti(OH)4, doped derivatives, or combinations thereof. These photocatalytic particles have a surface area per weight of no more than 15 m2/g. The coatable composition is then applied to uncoated base ceramic granules, resulting in intermediate coated granules. Finally, the intermediate coated granules are heated at a temperature of at least 700° C., leading to the formation of photocatalytic coated ceramic granules. These granules exhibit a Total Solar Reflectance (TSR) value of at least 0.7. This method offers an efficient and effective way to produce ceramic granules with enhanced photocatalytic properties.

Abstract: Surface structured articles comprising a polymer matrix and a dispersed phase, the article having first and second opposed major surfaces, at least a portion of the first major surface is a microstructured, anisotropic surface comprises features having at least one dimension in a range from 1 micrometer to 500 micrometers, wherein the dispersed phase comprises an antimicrobial material, and wherein at least a portion of the dispersed phase is present on the microstructured, anisotropic surface. Surface structured articles are useful, for example, for marine applications (e.g., surfaces in contact with water (e.g., fresh water, ocean water)) such as boats, ships, piers, oil rigs, decks, and roofing materials.
