    Abstract: A method is disclosed herein for treating a polymeric surface to resist non-specific binding of biomolecules and attachment of cells. The method includes the steps of: imparting a charge to the polymeric surface to produce a charged surface; exposing the charged surface to a nitrogen-rich polymer to form a polymerized surface; exposing the polymerized surface to an oxidized polysaccharide to form an aldehyde surface; and exposing the aldehyde surface to a reducing agent. Advantageously, a method is provided which produces surfaces that resist non-specific protein binding and cell attachment and that avoids the use of photochemical reactions or prior art specially designed compounds.

  • Patent number: 8541517
    Abstract: Stable, high performance polymer compositions including polybenzimidazole (PBI) and a melamine-formaldehyde polymer, such as methylated, poly(melamine-co-formaldehyde), for forming structures such as films, fibers and bulky structures. The polymer compositions may be formed by combining polybenzimidazole with the melamine-formaldehyde polymer to form a precursor. The polybenzimidazole may be reacted and/or intertwined with the melamine-formaldehyde polymer to form the polymer composition. For example, a stable, free-standing film having a thickness of, for example, between about 5 ?m and about 30 ?m may be formed from the polymer composition. Such films may be used as gas separation membranes and may be submerged into water for extended periods without crazing and cracking. The polymer composition may also be used as a coating on substrates, such as metal and ceramics, or may be used for spinning fibers. Precursors for forming such polymer compositions are also disclosed.
