The multiblock copolymer has a high ionic conductivity, high hydrophobicity, and good mechanical properties, can minimize crossover of methanol, and can be manufactured at a low cost. In addition, the structure of the multiblock copolymer can be varied to increase selectivity to a solvent used in a polymer electrolyte membrane.
