Title
(EN) METHOD FOR MODIFYING OF THE SEPARATION MATERIAL SURFACES
(FR) PROCÉDÉ DE MODIFICATION DE SURFACES DE MATÉRIAU DE SÉPARATION
Abstract
(EN)
A method comprising modifying of separation material surfaces, characterized by placing a flat membrane with generated hydroxyl groups, a modifying solution and dichloromethane in a glass vessel, tightly sealing said vessel and mixing said vessel's contents, preferably in a laminar flow cabinet in an atmosphere of inert gas, preferably argon or nitrogen, at a temperature of 20 to 40°C over a period of 1 to 6 h, wherein a solution is mixed throughout the entire reaction conduction time, the next step comprising removing said membrane from said glass vessel and washing said membrane with solvents by placing it, in order, in beakers filled with acetone, dichloromethane and water, and finally drying said membrane, preferably at a temperature of 40 to 60°C for 8 to 15 h.
(FR)
L'invention concerne un procédé comprenant la modification de surfaces de matériau de séparation, caractérisé en ce qu'il consiste à mettre une membrane plate avec des groupes hydroxyle générés, une solution de modification et du dichlorométhane dans un récipient en verre, à sceller hermétiquement ledit récipient et à mélanger lesdits contenus du récipient, de préférence dans une armoire à écoulement laminaire dans une atmosphère de gaz inerte, de préférence d'argon ou d'azote, à une température située dans la plage allant de 20 à 40 °C pendant une période allant de 1 à 6 h, une solution étant mélangée pendant tout le temps de conduction de réaction, l'étape suivante consistant à retirer ladite membrane dudit récipient en verre et à laver ladite membrane avec des solvants en la mettant, dans l'ordre, dans des batteurs remplis d'acétone, de dichlorométhane et d'eau, et enfin à sécher ladite membrane, de préférence à une température située dans la plage allant de 40 à 60 °C pendant une durée allant de 8 à 15 h.
