Patent

CA 2360322

A composite material having a support which is at least partially covered by a hydrophobic polymer comprising fluorine moieties obtainable by a process comprising the steps of: contacting the support with a crosslinkable compound having at least one olefinic double bond until the support at its surface is at least partially covered with the crosslinkable compound having at least one olefinic double bond, followed by fluorination of the support at least partially covered with the crosslinkable compound having at least one olefinic double bond, removal of unreacted material, if any, and recovering the composite material having a support which is at least partially covered by a hydrophobic polymer comprising fluorine moieties.

L'invention concerne un matériau composite comprenant un support au moins partiellement recouvert d'un polymère hydrophobe, lequel comprend des fractions de fluor et s'obtient au moyen d'un procédé comprenant les étapes suivantes consistant: à mettre en contact le support avec un composé réticulable possédant au moins une liaison double oléfinique, jusqu'à ce que le support soit, au niveau de sa surface, au moins partiellement recouvert de ce composé réticulable possédant au moins une liaison double oléfinique, puis à fluorer le support au moins partiellement recouvert du composé réticulable, à enlever le matériau n'ayant pas réagi, le cas échéant, et à récupérer le matériau composite dont le support est au moins partiellement recouvert d'un polymère hydrophobe comprenant des fractions de fluor.
