Functional Polymeric Ionic Liquids
Abstract: Polymers that contain ionic liquid constituents retain many of the properties of ionic liquids, including ionic conductivity. We have recently found that a polymerized cation (such as imidazolium) is an excellent host for any associated anion. As a result, polymeric ionic liquids (PILs) are not just solid counterparts to ionic liquids, but are also excellent vectors for the inclusion of a variety of functionalities ranging from multi-valent ions for batteries to magnetic anions. Moreover, PIL block copolymers allow orthogonal control over mechanical and morphological properties, ultimately leading to a conceptual framework for processable, tunable, multifunctional materials.
In this talk, I will discuss a class of protic PILs based on imidazolium cations thatexhibit high ionic conductivities in the solid state. Further, I will also discuss PILs that are useful for applications ranging from magnetic materials to thermoelectrics.
