A method of manufacturing an anion exchange membrane, the method comprising:
- preparing a composition for forming an anion exchange polymer, comprising a first monomer represented by Formula A, a crosslinking agent represented by Formula B, a photoinitiator, and a solvent;
- impregnating a porous polymer support with the composition for forming an anion exchange polymer, to fill at least a portion of a surface of the porous polymer support and interiors of pores of the porous polymer support with the composition for forming an anion exchange polymer;
- pressing a film onto at least the surface of the porous polymer support filled with the composition for forming an anion exchange polymer, to produce a laminate in which the film and the porous polymer support are laminated together;
- irradiating the laminate with light and crosslinking the composition for forming an anion exchange polymer to form, on at least a portion of the surface of the porous polymer support and the interiors of the pores of the porous polymer support, an anion exchange polymer that is a crosslinked product of the composition for forming an anion exchange polymers of the pores;
- and
- forming an anion exchange membrane by peeling off the film from the porous polymer support of which at least a portion of the surface and the interiors of the pores is filled with the anion exchange polymer:
- wherein, in Formulae A and B,
- Vi is a vinyl group,
- R11 to R16, R21, and R22 are each independently selected from hydrogen, deuterium, a substituted or unsubstituted C1-C20 alkyl group, and a substituted or unsubstituted C2-C20 alkenyl group,
- R11 and R12 are optionally bonded to each other,
- R13 and R14 are optionally bonded to each other,
- R21 and R22 are optionally bonded to each other,
- a4 is an integer from 0 to 4,
- L1 and L2 are each independently selected from a single bond and a substituted or unsubstituted C1-C20 alkylene group,
- X− and Y− are each independently selected from F−, Cl−, Br− and I−, and
- each of n1, n2, m1, and m2 is an integer from 0 to 10.
