ANION-EXCHANGE MEMBRANE, AND ELECTROCHEMICAL ELEMENT AND ELECTROCHEMICAL DEVICE HAVING SAME

摘要

Provided is an anion-exchange membrane including: a substrate composed of a film of ultrahigh molecular weight polyolefin; and a graft chain having the following structural unit.;L₁ to L₅ are each independently a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkanol group having 1 to 4 carbon atoms, or a specific functional group including an anion-exchange group, and an example of the functional group is -Z₂-M₁-Z₁(R₁)(R₂)(R₃). R₁ to R₃ are directly bonded to Z₁ and are each independently an alkyl group having 1 to 8 carbon atoms or an alkanol group having 1 to 8 carbon atoms. M₁ is a linear hydrocarbon chain having 3 to 8 carbon atoms, Z₁ is a nitrogen atom or a phosphorus atom, and Z₂ is a nitrogen atom bonded to one hydrogen atom, an oxygen atom, or a sulfur atom. L₆ is a hydrogen atom, a methyl group, or an ethyl group.
