Abstract: A hollow-fiber membrane is presented. The hollow fiber membrane, includes a copolymer including sulfone structural units having a formula (I) and zwitterion-functionalized structural units having a formula (II). Method of making the hollow-fiber membrane is also presented.

Abstract: Provided herein are copolymers and copolymer compositions that are both hydrophilic and oleophobic. The copolymers include structural units derived from a fluoroalkyl monomer and a zwitterionic monomer. It further relates to membranes formed by coating a porous substrate with the copolymeric compositions. The copolymeric coating imparts hydrophilicity and oleophobicity/oil-tolerance to the membranes. The uses of such membranes as microfiltration membrane or ultrafiltration membrane are also provided.
