Abstract

Des surfaces de polymères, en particulier de polyesters, peuvent être fluorées au moyen du dépôt d'un fluorocarbone sous forme de solution. Le fluorocarbone peut se composer d'un fluoropolymère amorphe, tel que le copolymère de tétrafluoréthylène et de bis-2,2-trifluorométhyle-4,5-difluoro-1,2-dioxyde commercialisé sous la marque déposée TEFLON AF R, soluble dans des alcanes fluorés et d'autres liquides fluorés tels que ceux commercialisés sous la marque déposée FLUORINERT R. Des polyesters à surface fluorées, en particulier sous forme de tissus tricotés, sont utiles comme greffes vasculaires: la surface fluorée réduit les effets thrombogènes et l'activation du système complémentaire. Les inconvénients des procédés de fluoration de surfaces connus, tels que les procédés à plasma froid ou à décharge luminescente, sont ainsi évités.
