Structure-morphology-property relationships in polymerized ionic liquids

The rising energy needs of modern society continue to provide significant impetus for extensive research and development in energy storage devices. Polymer electrolytes play a key role in these devices.

Polymerized ionic liquids are a new class of polymer electrolytes that exhibit both the outstanding mechanical characteristics of polymers and unique physic-chemical properties of molecular ionic liquids in the same material.

“They have shown remarkable advantages when employed in dye-sensitized solar cells, lithium batteries, actuators, field-effect transistors and electrochromic devices,” Sangoro says. “Despite their prospects as ideal polymer electrolytes, the key structure-morphology-property relationships in polymerized ionic liquids are not yet understood.”

The goal of Sangoro’s Collaborative Cohort project is to obtain a fundamental understanding of the impact of molecular structure, morphology and dynamics on charge transport in polymerized ionic liquids. Sangoro hopes details of the underlying mechanisms of ion transport in polymerized ionic liquids will be unraveled by complementing results from broadband dielectric spectroscopy with insight from the proposed neutron scattering, dynamic-mechanical spectroscopy, NMR and calorimetry experiments.

The experimental data obtained from Sangoro’s Collaborative Cohort project has led to one proposal submitted to the Army Research Office. The support from Science Alliance within the framework of this project was instrumental in enabling Sangoro to win a $348K single-investigator grant from the National Science Foundation in May 2015.
