Beschreibung
Zusammenfassung:	The present invention is directed to a practically universal surface modification process and the materials thereby obtained. In general, the process includes initial epoxy modification of a substrate surface by attachment of an epoxy-containing polymer to the surface. Following attachment of the polymer, still-existing epoxy groups on the polymer may then cross-link the polymer to form a unified anchoring layer on the surface. Other epoxy groups in the anchoring layer, not utilized in forming the layer may be used to graft surface modifying materials to the surface. For instance, macromolecules, biomolecules, polymers, and polymerization initiators may be grafted to the surface via the anchoring layer. La présente invention a trait à un procédé de modification de surface quasi-universel et les matériaux obtenus par ce procédé. De manière générale, le procédé comprend la modification époxydique de la surface d'un substrat par la fixation d'un polymère époxydique à la surface. Suite à la fixation du polymère, des groupes époxydiques subsistant sur le polymère peuvent alors réticuler le polymère pour former une couche d'ancrage unifiée à la surface. D'autres groupes époxydiques dans la couche d'ancrage, non utilisés dans la formation de la couche peuvent être utilisés pour assurer la greffe des matériaux de modification superficielle à la surface. Par exemple, des macromolécules, des biomolécules, des polymères, et des initiateurs de polymérisation peuvent être greffés à la surface via la couche d'ancrage.
