ASYMMETRIC POROUS MEMBRANE WITH EPOXIDE RINGS

摘要

The invention herewith described refers to the asymmetric porous membrane with epoxide rings. Such membrane can be prepared using a simplified method which omits many additional steps carried out in order to functionalize existing asymmetric membranes. According to this method a homogeneous polymerizable solution comprising a reactive component with epoxide rings, a crosslinker, a glassy polymer, and a solvent, is formed into a shaped article, exposed to a source of irradiation to polymerize and crosslink the reactive components, and immersed into a coagulation bath to form said membrane. Epoxide rings can be converted into desired functional groups using simple chemical reactions and such membranes can be utilized for a broad range of separation processes including ultrafiltration, membrane adsorption for chemical or biochemical applications, or in sensing devices based on membranes and thin films.
