Abstract
The present invention discloses a class of nitrogen-containing heterocyclic polymers, a class of polymer membranes and applications thereof, wherein the nitrogen-containing heterocyclic polymers comprise structural units of following general formula:A nitrogen-containing heterocycles in the class of nitrogen-containing heterocyclic polymers have large steric hindrance and electron donating groups, which are beneficial for further improving stability of materials. The class of nitrogen-containing heterocyclic polymers can be formed membranes using commonly industrial methods such as coating. The prepared polymer membranes have advantages such as large scale, thin thickness, high strength, and excellent ion conductivity, which can be used in fuel cells, water electrolysis hydrogen production, metal-air batteries, flow batteries, carbon dioxide reduction, supercapacitors, electrodialysis, water treatment, membrane humidification, nickel hydrogen batteries, zinc manganese batteries, acid separation, salt lake lithium extraction, and other fields.
