Surface zwitterionicalization of poly(vinylidene fluoride) porous membranes by post-reaction of the amphiphilic precursor

► A facile method to endow porous membranes with coverage of zwitterion was described. ► PDMAEMA was transited to zwitterion by using 3-bromopropionic and 1,3-propanesultone. ► The modified membranes showed increased protein retention while decreased water flux. A facile method to endow porous membr...
