Anion conducting electrolyte membrane and manufacturing method thereof

摘要

An anion conducting electrolyte membrane with high performance where the electric conductivity and the water uptake are balanced, and a method of manufacturing the same are disclosed. The anion conducting electrolyte membrane comprises: a polymeric material which consists of fluorine polymer, olefinic polymer, or aromatic polymer; weak base quaternary salt obtained by the reaction of grafts introduced by graft polymerizing vinyl monomer which contains halogenated alkyl groups using radiation and strong organic bases.

1. A method of manufacturing an anion conducting electrolyte membrane comprising:
graftpolymerizing a vinyl monomer which contains halogenated alkyl groups attached on a polymeric material which consists of fluorine polymer, olefinic polymer or aromatic polymer using radiation; quaternizing at least one part of the grafts attached on the polymeric material introduced by the radiation graftpolymerization with a plurality of strong organic bases, including controlling the basicity of a quaternary salt resulting from the quaternizing with the plurality of strong organic bases; and substituting halogen anions of the quaternized grafts with hydroxide ions.
