Abstract
Methods are disclosed for modifying at least a portion of a porous polymeric surface. Such methods include contacting the porous polymeric surface with at least one polyelectrolyte, resulting in the physical adsorption of at least one polyelectrolyte onto the porous polymeric surface to form a charge modified surface. Such coated surfaces may be part of a device or apparatus, including electroosmotic pumps.
