摘要： A method for modifying a substrate containing a natural polymeric material to improve its interaction with other materials, the method comprising: A) Treating the substrate containing the natural polymeric material with a modifying agent selected from the group consisting of organo-functional coupling agents and multi-functional amine containing organic compounds; and B) optionally exposing the substrate containing natural polymeric material with one or more treatments selected from the group consisting of: i) subjecting the substrate to extraction with a solvent to reduce the content of extractable materials associated with the natural polymeric material prior to or during treatment with the modifying agent; ii) treatment with a physical field selected from static physical fields, high-frequency alternating physical fields and combinations of two or more thereof either prior to, during or after treatment with the modifying agent; and iii) oxidation of at least part of the natural polymeric material prior to or during treatment with the modifying agent.

摘要： A method of modifying a polymeric surface of a substrate including: (iii) providing the polymeric surface with functional groups; and (iv) contacting the surface with (a) a polyamine compound reactive with the surface functional groups said polyamine comprising at least four amine groups including at least two amine groups selected from primary and secondary amine groups and (b) a crosslinking agent reactive with the polyamine; to provide a crosslinked network grafted to the substrate surface.
