Microporous hydrophilic membrane |
摘要 |
A microporous, hydrophilic membrane (I) comprises polysulfone and/or polyetherketone having covalently bonded substituents and containing at least a hydroxyl group, carboxyl group and/or an amine group. Independent claims are included for; (1) A process for the preparation of the membrane (I) by substituting the polymer by reaction with substances leading to the introduction of a hydroxyl, carboxyl or amine group, dissolving the polymers in a solvent, forming the membrane, preferably by applying the solution to a support or by spin coating and precipitation by means of a precipitating agent that is miscible with the solvent. (2) A biohybrid hollow organ comprising at lest a chamber for the uptake of organic cells whereby the chamber walls are at least partially formed from the membrane (I), and (3) A process for the exchange of material for using the membrane (I). |
