Abstract
Filter media for use in liquid filters and liquid filters are provided that include a substrate, such as a porous membrane, and nanoparticles incorporated into the substrate. The nanoparticles may comprise nanoparticles, nanofibers or mini fibers that have at least one dimension less than about 20 microns. The nanoparticles are bonded to the fibers within the substrate and are dispersed “in depth” within the substrate, which improves the performance characteristics of the material for a number of different applications. For example, the nanoparticles increase the overall surface area within the substrate, which may increase its filtration efficiency and allow for the capture of submicron contaminants without significantly compromising other factors, such as bubble point or through-put across the filter.
