Ionic liquids and Their Application in Green Chemistry covers the synthesis and characterization of a broad range of ionic liquids (ILs) and their polymers, along with their application in multiple areas for nanomaterials and environmental sustainability. The book provides reference material for future research in IL-based technologies for environmental and energy applications. It covers not only the conventional IL applications. but also advanced IL polymer-based materials and their application in energy storage and energy generator applications. Finally, the book discusses the major fields of application of IL-based materials in synthesis of nanomaterials and the role in graphene synthesis and its composites. Written by eminent scholars and leading experts from around the world, this book brings the literature up to date on the most recent progress in the field of IL based materials and their applications for the environmental sustainability.
