Abstract
The present invention provides materials and methods of making materials, where at least one surface of the material utilizes an emulsion to controllably release active agents, which can include hydrophilic agents, into the surrounding environment. Preferably, the materials are ‘slippery’ in that liquid droplets and other compounds, such as aqueous fluids, organic compounds and microorganisms, are able to easily slide off the surface without adhering to the surface. The active agents released by the emulsion may include antimicrobial agents, antifungal agents, antibacterial agents and other molecules that can kill or otherwise reduce the number of the pathogens. The resulting materials have improved anti-fouling behaviors compared to many other existing types of anti-fouling surfaces.
