Key Points

To explore the relationship between structure and morphology in hydrated polyelectrolyte membranes.
Examined structure–morphology relationships in two types of ionene membranes: poly(benzimidazolium) and poly(bis-arylimidazolium).
Analyzed the alkaline stability of the membranes.
Investigated the hydration characteristics of the membranes.
Identified key structural features influencing the morphology of the membranes.
Demonstrated that the composition affects the alkaline stability of the membranes.

Implication

This research reveals structure–morphology connections in hydrated anion exchange membranes, suggesting benefits for polyelectrolytes.

Abstract

Ease in preparation and the alkaline stability characteristics spurred immense interest in polyelectrolytes composed of poly(benzimidazolium) (HMT-PMBI) and poly(bis-arylimidazolium) (PAImMM) Ionene anion exchange membranes. The present work emphasises the structure...
