Electron beam-induced modification of membranes by polymers

摘要

The present invention relates to a process for producing a microporous membrane having fixed on its surface an electron beam cross-linked polymer, comprising providing a microporous starting membrane, impregnating the membrane with an impregnating solution comprising a solvent and a polymer dissolved or dispersed therein to provide an impregnated membrane, and to irradiate the impregnated membrane with electron radiation to provide a microporous membrane on the surface of which the electron beam crosslinked polymer is, and a microporous membrane produced by this method, and the use of such a membrane.
