Ionic liquids have been researched widely as possible green designer materials for a wide variety of applications. Recent effort has focused more directly on ionic liquids that are confined in some way, such as within polymer matricies. Additionally, researchers have started to explore the properties of ionic liquids with multiple types of anions or cations, such as mixed ionic liquids. In this project, we examine the effect of such complexity on the properties of ionic liquids, with a particular focus on applications such as carbon capture.
