Examples
example 1
[0022] ①Dissolve 1 part of polybenzimidazole containing sulfonic acid side groups in 10 parts of organic solvent dimethylformamide to form a uniform mixture;
[0023] ② Add 8 parts of silicon dioxide to the mixture to form a suspension;
[0024] ③ Mix the suspension with 180Mpa ultra-high pressure;
[0025] ④Introduce ultrasonic waves, apply ultrasonic vibration force to suspended matter, and carry out nano-crushing of suspended matter and whole-chain treatment of aromatic heterocyclic polymers;
[0026] ⑤ After casting the slurry formed above to form a film at room temperature, solidify at room temperature for 2 hours, then solidify at 100°C in an inert atmosphere for 4 hours, cool to room temperature, and remove the membrane in water to obtain a methanol permeation-resistant proton exchange membrane.
example 2
[0028] ① Dissolving 1 part of polyphenylquinoxaline containing sulfonic acid side groups in 12 parts of organic solvent dimethylacetamide to form a uniform mixture;
