COMPOSITES COMPRISING NOVEL RTIL-BASED POLYMERS, AND METHODS OF MAKING AND USING SAME

摘要

The invention includes compositions comprising curable imidazolium- functionalized poly(room-temperature ionic liquid) copolymers and homopolymers. The invention further includes methods of preparing and using the compositions of the invention. The invention further includes novel methods of preparing thin, supported, room-temperature ionic liquid-containing polymeric films on a porous support. In one embodiment, the methods of the invention avoid the use of a gutter layer, which greatly reduces the overall gas permeance and selectivity of the composite membrane. In another embodiment, the films of the invention have increased gas selectivity and permeance over films prepared using methods described in the prior art.
