Morphology and ionic conductivity of sulfonated block copolymers containing mixed ionic liquids |
| 초록 |
Block copolymer electrolytes are receiving great attention for future energy storage systems. Owing to their self-assembly behavior into various morphologies, structure-transport relationship has been an interesting subject to improve ionic conductivity of block copolymer electrolytes. The introduction of ionic liquids into charged block copolymer has offered wide-tunable morphologies via the control of long-range interactions in ionic domains. Herein, we investigate acid-tethered block copolymers comprising mixed ionic liquids. Two different ionic liquids having different anions at a fixed cation were prepared and added into the block copolymer by varying the molar ratio. It has been revealed that the miscibility and solvation energies of ionic liquid anions considerably alter the distribution of ionic liquids in nanodomains, thereby changing the resultant morphologies. This resulted in a variable ionic conductivity of block copolymer electrolytes by several orders of magnitudes. |
