Title (EN) FLUORINATING POLYMER SURFACES
(FR) SURFACES DE POLYMERE FLUOREES
Abstract:
(EN) Surfaces of polymers, particularly polyesters, can be fluorinated by deposition of a fluorocarbon from solution. The fluorocarbon may be an amorphous fluoropolymer, such as the copolymer of tetrafluoroethylene and $i(bis)-2,2-trifluoromethyl-4,5-difluoro-1,2-dioxole sold under the trademark TEFLON AF R, which is soluble in fluorinated alkanes and other fluorinated liquids such as those sold under the trademark FLUORINERT R. Surface-fluorinated polyesters, particularly in knitted fabric form, are useful as vascular grafts: the fluorinated surface reduces thrombogenicity and complement activation. The disadvantages of known surface fluorination methods, such as the cold plasma or glow discharge process, are avoided.
(FR) 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 $i(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.
