High performance membrane |
摘要 |
The present invention relates to a method for modifying a porous membrane, comprising steps wherein (a) a porous membrane carrier (A) having an open pore structure is impregnated with a solution (X) comprising a polymer (B-1) in a solvent (X-1) in which the polymer (B-1) is soluble, thus forming a porous membrane carrier impregnated with the polymer solution (X), and at least part of the polymer (B-1) comprised by the impregnated solution is precipitated from the solution by quenching with a liquid (Y) comprising a non-solvent (Y-1) for said polymer. The invention also relates to a micro-porous membrane comprising a porous membrane carrier (A) and a polymeric material (B) comprising a polycondensation polymer intimately divided throughout the porous membrane carrier, wherein the polymeric material comprises a polycondensation polymer, as well as to a process for preparing the said membrane and to the use thereof. |
