摘要: One aspect of the invention is a method for making a composite material comprising a porous support and a porous nanoweb comprising: (a) providing a porous support; (b) providing a gelling mixture comprising one or more solvent(s) and one or more organogelator(s); (c) applying the gelling mixture to the porous support; (d) inducing said organogelator(s) to form a nanoweb gel; and (e) removing the solvent(s) from the nanoweb gel to provide a dry porous nanoweb coating on said porous support; wherein the one or more solvent(s) is a supercritical fluid. Preferably the supercritical fluid is carbon dioxide. Other embodiments of the invention include a nanoweb composite provided by the method.

摘要: The invention is a process useful for providing a treated support comprising a porous nanoweb coating wherein the treated support is characterized by a biofilm cell count of less than 50% that of an untreated porous support control. The process is useful for modifying porous materials, such as filter media and barrier fabrics to provide resistance to biofouling. The porous nanoweb coating is comprised of fibrous structures derived from gelation and drying of supramolecular assemblies of non-covalently bonded organogelators. Typical organogelators useful in the invention include those that assemble via hydrogen bonding and π-stacking.
