Abstract:
PURPOSE: An electrolyte is provided to improve hydrogen ion conductivity by controlling the size and shape of an ionic domain in polymer transferring hydrogen ions. CONSTITUTION: An electrolyte consists of a block copolymer with ionic domain transferring hydrogen ions on the outside thereof. The ionic domain includes a block copolymer with a thickness of 1.0-10.0nm. The block copolymer forms an ionic domain by a sulfonated block. A self-assembling block copolymer consists of an ionic shell which transfers a core and hydrogen ions. The thickness of the ionic shell is 1-10nm. The ionic shell consists of a sulfonated block.
