The present invention provides gels, solutions, films, membranes, compositions, and other materials containing polymerized and/or non-polymerized room-temperature ionic liquids (RTILs). These materials are useful in catalysis, gas separation and as antistatic agents. The RTILs are preferably imidazolium-based RTILs which are optionally substituted, such as with one or more hydroxyl groups. Optionally, the materials of the present invention are composite materials comprising both polymerized and non-polymerized RTILs. The RTIL polymer is formed from polymerized RTIL cations typically synthesized as monomers and polymerized in the presence of the non-polymerized RTIL cations to provide a solid composite material. The non-polymerized RTIL cations are not covalently bound to the cationic polymer but remain as free cations within the composite material able to associate with charged subunits of the polymer. These composite materials are useful in catalysis, gas separation, and antistatic applications.
