Zusammenfassung:The invention provides a high-alkali-resistance ionic membrane with micropores. The high-alkali-resistance ionic membrane is formed by quaternizing a polymer main chain as shown in a formula (I), a formula (II) or a formula (III), wherein a is any integer greater than or equal to 1; b is any integer greater than or equal to 0; a is a rigid distortion structure unit, B is an aromatic hydrocarbon structure unit, and C is a nitrogen-containing heterocyclic ring unit. According to the high-alkali-resistance ionic membrane with the micropores, winding and stacking of a polymer main chain are reduced through a rigid distortion structure, and a large number of micropores between molecular chains are constructed; the nitrogen-containing heterocyclic ring has relatively large steric hindrance and electron-donating groups, so that the chemical stability of the ionic membrane is improved; the composite material has the advantages of high ion selectivity, high ion conductivity, long service life, good mechanical property
