Abstract:
Various types of polymerizable ionic liquid monomers and their polymers are synthesized for the potential applications in electrolyte components of electroactive devices. To perform both traditional chain-growth radical polymerizations and step-growth polycondensations, proper monomer functionalities are introduced to the ionic liquid monomers. For the polymerized ionic materials, structure-property relationships for both pendant and main-chain polycations with various counter-anions are carefully investigated by various spectroscopic and thermal analyses. Ionic polymers with pendant imidazolium units show different morphologies and thermal properties through the different pendant structures; some structural characteristics are important to the property changes. Main-chain polycations with various anions show remarkable morphology and electrical property changes; a lamellar microphase-separation gives a big increase in ionic conductivity. Copolyesters of imidazolium-ionic and PEG blocks show interesting thermal behaviors and ionic conductivity changes by varying a chemical structure. The potential applications of the synthesized polymers are expanding to energy storage and harvesting devices, such as full-solid electrolytes for supercapacitors, dye-sensitized solar cells and organic/inorganic hybrid solar cells.
