A new series of green solvents that constituted with ionic liquids (ILs) and dimethyl acetamide (DMAc) were developed as good solvents for zwitterionic copolymers, and the dissolutions of amphiphilic copolymers carrying carboxylbetaine and sulfonatebetaine in these new solvents were studied. It was determined that the commonly found ILs such as 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF...
A facile method to endow porous membranes with high coverage of zwitterionic components on surface was described. The amphiphilic precursor poly(vinylidene fluoride)-graft-N,N-dimethyl aminoethyl methacrylate (PVDF-g-PDMAEMA) was firstly synthesized via ATRP method and then blended with PVDF to prepare flat membranes. The 3-bromopropionic and 1,3-propane sultone were then used as quaternization agent...
