Patent

CA 2694273

The invention relates to an hydrophilic membrane comprising a membrane carrier and a hydrophilic coating with good properties. The coating may comprise covalently bound inorganic-organic hybrid material; or the coating may comprise ring-opening polymerized components like epoxy resins. The coating composition preferably is applied in a solvent, the solvent is evaporated, and the coating is cured with UV radiation. The hydrophilic membrane is very useful in water purification, and in other applications.

L'invention concerne une membrane hydrophile comprenant un support de membrane et un revêtement hydrophile ayant de bonnes propriétés. Le revêtement peut comprendre un matériau hybride inorganique-organique lié par covalence ; ou le revêtement peut comprendre des composants polymérisés par décyclisation comme les résines époxy. La composition de revêtement est, de préférence, appliquée dans un solvant, le solvant est chassé par évaporation, et le revêtement durci par un rayonnement UV. La membrane hydrophile est très utile pour la purification de l'eau, et dans d'autres applications.
