Synergistic Hydrogen‐Bonding and Covalent Crosslinking in Polybenzimidazole Membranes for Wide‐Temperature Anhydrous Fuel Cells

open access: yesAdvanced Science, EarlyView.
A dual‐network architecture combining a thermally reinforced hydrogen‐bonding matrix with an amine‐anhydride covalent framework was constructed in Tröger's Base (TB)‐functionalized polybenzimidazoles. This design yielded the TBAm‐PBI‐TB membrane with high acid uptake (469.5%), anhydrous conductivity (264.7 mS cm−1), and robust stability.

Nanoscale Covalent Organic Framework Confinement Enables Ultratough and Hyperelastic Hydrogels Applied as High‐Performance Electrolytes

open access: yesAdvanced Science, EarlyView.
Confinement by nanoscale covalent organic frameworks reinforces hydrogels, imparting exceptional mechanical strength and ionic conductivity for high‐performance electrolyte applications. ABSTRACT Hydrogels are widely applied in various fields, including energy storage and flexible electronics. However, their mechanical properties often fail to meet the
