A membrane useful in gas separation, the membrane comprising a cross-linked polysiloxane structure having a cross-link density of about 0.1&#xd7;10mol/cmto about 6&#xd7;10mol/cm, where, in particular embodiments, the cross-linked polysiloxane structure has the following general structure: wherein R, R, R, R, R, and Rare independently selected from hydrocarbon groups having at least 1 and up to 6 carbon atoms; Aand Aare independently selected from cyclic hydrocarbon groups; Land Lare linking groups or covalent bonds; n is an integer of at least 1; r and s are independently selected from integers of at least 1; and p is an integer of at least 10. The invention also includes methods for making and using the above-described membranes for gas separation.

Cross-linked polymeric membranes for carbon dioxide separation

An ionic liquid composition having the following chemical structural formula: wherein R, R, R, and Rare independently selected from hydrocarbon groups containing at least 1 and up to 20 carbon atoms, and Xis a cyclic anion that possesses a negatively-charged group reactive with a gaseous electrophilic species, particularly carbon dioxide or sulfur dioxide. Methods for capturing a gaseous electrophilic species, such as COor SO, by contacting the gaseous electrophilic species with an ionic liquid according to Formula (1) are also described.
