Abstract: The present disclosure is related to a polymeric membrane having a first surface and a second surface and a wall extending between the first and second surface, the membrane comprising pores on the first and second surfaces and throughout the wall, the membrane comprising a modified surface, the modified surface comprising acrylate and/or methacrylate polymers and/or copolymers, wherein the modified surface extends at least over the first and/or the second surface, and over the pores of at least 50% of the thickness of the wall. Furthermore, the present disclosure provides a method for producing such a membrane as well as a use of the membranes as disclosed herein for purification of aqueous media such as in biopharmaceutical applications.
