Patent

CA 2551106

A lubricous coating composition and methods for using same are provided. Specifically, a composition suitable for providing hydrophobic polymer surfaces with lubricious coatings is described wherein a polyolefin surface is reiteratively treated with hydrophilic polymer solutions and cross-linking solutions. Methods for reiterative coating polymer surfaces are also provided including methods wherein the hydrophobic polymer surface is pretreated using plasma energy.

L'invention concerne une composition de revêtements lubrifiés et des procédés servant à utiliser cette composition. Cette composition permet d'obtenir des surfaces polymères hydrophobes pourvues de revêtements lubrifiés, ce qui consiste à traiter de façon répétée une surface de polyoléfine par des solutions polymères hydrophiles et des solutions de réticulation. Elle concerne également des procédés servant à revêtir de façon répétée des surfaces polymères, y compris des procédés selon lesquels la surface polymère hydrophobe est traitée préalablement au moyen d'une énergie plasmique.
