Imidazolyl ionic liquid and application thereof in alkaline anion exchange membrane

The invention relates to an imidazolyl ionic liquid and preparation of an alkaline anion exchange membrane with the same. The preparation includes the following three steps: synthesis of an imidazolium salt, synthesis of imidazolyl cross-linked copolymer, and preparation of an imidazolyl cross-linked type alkaline anion exchange membrane, and at the same time on the basis, the step of preparation of an oxyhydrogen type imidazolyl cross-linked alkaline anion exchange membrane can be added so as to further improve the conductivity of the membrane. The ionic liquid involved in the invention substitutes the 2-position of an imidazole ring, thus avoiding imidazole group ring opening and degradation occurring under the attack of hydroxyl ions, and enhancing the stability of the imidazole group. And the method of applying the imidazolyl ionic liquid to preparation of the alkaline anion exchange membrane has the advantages of environmental friendliness, simple process, and can realize large-scale production. The prepared imidazolyl cross-linked alkaline anion exchange membrane has a uniform, smooth and compact surface, and has good conductivity, good thermal stability and chemical stability. By applying the alkaline anion exchange membrane to alkaline direct alcohol fuel cells, a single battery has the advantages of high performance, and obvious performance advantages, etc.
