Abstract
A method to impart increased lubricity to the surface of a polymeric substrate includes contacting the substrate with a solution of a hydrophilic polymer in a solvent and heating the substrate to evaporate the solvent. The substrate retains a coating of the hydrophilic polymer, which, when dry, has about the same lubricity as the uncoated substrate. When wet, the coating becomes significantly more lubricious than when dry. The invention includes articles which have a lubricious surface when wet prepared by the method of the invention.
