Abstract
An anion exchange membrane and a method of preparing the same are provided. The anion exchange membrane includes a porous polymer support, and an electrolyte containing an anion exchange polymer, wherein the electrolyte is located at least on a portion of the surface and the inside of pores of the porous support, and the anion exchange polymer may be a crosslinked product of a composition including a crosslinkable monomer represented by Formula 1 and an ionic monomer represented by Formula 2. In Formulas 1 and 2, A, R1, R2, R3, R4, X−, Y−, p, q, and r are as disclosed in the specification.
