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.
