Results and discussion

Results and discussion

conclusion PIL–IL composites are very promising materials for gas separation membranes since their properties can be highly tuned by the incorporation of free ionic liquid.  These composite membranes the obtained　CO 2 /N 2 permselectivity is higher than that of both pure polymeric ionic liquid and pure ionic liquid. It is possible to choose an ionic liquid with appropriate properties for a desired separation.
