Magnetic field‐induced alignment of polybenzimidazole microstructures to enhance proton conduction

Aligned polymer microstructures in the field of biomaterials, semiconductors, and ion-conductive membranes expand steadily. Here, an alternative aligned polybenzimidazole (WM PBI) microstructures fabrication strategy based on the utilization of a weak magnetic field (0.3 T) via the solvent casting m...
