Electron Beam‐Based Functionalization of Poly(ethersulfone) Membranes

Abstract

Poly(ethersulfone) membranes were surface modified in a one-step procedure. For this purpose, the membranes were soaked with aqueous solutions of different low-molecular weight molecules bearing diverse hydrophilic functionalities and subject to electron beam treatment. No catalysts, photoinitiators, organic solvents or other toxic reagents were used, and no additional synthetic or purification steps were required.
