Block copolymer electrolyte composite membranes and methods of producing the same

摘要

The present invention relates to block copolymer electrolyte composite membranes with improved ionic conductivity. The block copolymer electrolyte composite membrane in accordance with an aspect of the present invention can comprise a plate-like inorganic filler as surface-modified with a sulfonic group; and a block copolymer comprising at least one selected from the group consisting of a sulfonic group, a carbonic acid group, and a phosphoric acid group.

主权项

1. A penta-block copolymer electrolyte composite membrane, which comprises:
a platelet inorganic filler surface-modified with a sulfonic group; and a penta-block copolymer comprising at least one selected from the group consisting of a sulfonic group, a carbonic acid group, and a phosphoric acid group, wherein the penta-block copolymer consists of poly((t-butyl-styrene)-b-(ethylene-r-propylene)-b-(styrene-r-styrene sulfonate)-b-(ethylene-r-propylene)-b-(t-butyl-styrene)).
