Abstract:

A novel cellulose ester grafted ionic liquid(IL) copolymer, 1-vinyl-3-butylimidazolium tetra-fluoroborate(VbimBF4) grafted cellulose butyrate acrylate(CBA)(CBA-g-VbimBF4) was synthesized by free radical graft copolymerization. The CBA-g-VbimBF4 membranes exhibited improved CO2 permeability over the conventional cellulose acetates. Furthermore, four kinds of ILs, EmimBF4, BmimTf2N, BmimAc and EmimAc were incorporated into CBA-g-VbimBF4 copolymer, and obtained CBA-g-VbimBF4/ILs composite membranes exhibited both high permeability and permselectivity for CO2.

Key words: Cellulose, Ionic liquid, Composite membrane, CO2-favored permeation
