摘要: Abstract Herein, a series of composite membranes based on sulfonated poly(ether ether ketone) (SPEEK) and imidazole-type ionic liquid (ImIL) are prepared through IL-swollen method as anhydrous electrolytes for fuel cell. The IL loading amount is accurately controlled by preparation conditions (e.g., ultrasonic power, treatment temperature, time). influence physicochemical properties membrane systematically investigated. enriched into the clusters SPEEK matrix driven electrostatic attractions, thereby broadening them to form inter-connected channels. provides hoping sites low-energy-barrier paths imidazole-sulfonic acid pairs membrane. Through channels, these facile pathways significantly enhance conductivity Particularly, containing 43% achieves 52 times higher (9.3 mS cm –1 ) than that control (0.179 mS cm at 140 °C. Increasing will further elevate conductivity. dynamic release concomitant Moreover, another team solution casting exploring microstructure, retention ability, IL-incorporated
