IONIC LIQUIDS IN ELECTROACTIVE DEVICES

ARMY RESEARCH OFFICE MURI

 

                        This interdisciplinary effort involving collaborators at Pennsylvania State University, the University of Pennsylvania, Drexel University and Virginia Tech investigates the fundamental issues relating to combinations of ionic liquids with polymers and incorporation of ionic liquid-type moieties into polymers for possible applications in actuators and other electroactive devices.

                        The synthetic team, which includes students of Prof. Gibson and Prof. Tim Long, explores molecular designs and synthetic strategies to produce IL-containing polymers with unique macromolecular morphologies and enhanced mechanical and transport performance.

                        The Gibson group is currently collaborating with Prof. Ken Wagener’s group at the University of Florida in use of ADMET (acyclic diene methathesis) polymerization to produce such controlled structure polymers.  We are also studying polyacrylates bearing imidazolium side chains.

                        These polymers are carefully examined in Prof. Ralph Colby’s lab at Penn State for their ionic conductivities and in Prof. Karen Winey’s lab at the University of Pennsylvania for their morphological structures. The best candidates are then examined in terms of their actuator performance at Penn State in Prof. Qiming Zhang’s laboratories.
