Highly Anion Conductive Cellulose Realized by One-Step, Facile, and Effective Introduction of Ammonium and Phenyl Alkyl Groups.

ABSTRACT: Anion exchange membranes (AEMs) have attracted attention due to their applications in water electrolyzers, metal-air batteries, and redox flow batteries. However, developing AEMs with cost-effective and environmentally friendly methods is highly challenging. Herein, we demonstrate that a novel, one-step molecular modification of cellulose (powder, degreasing cotton, and natural cotton) provides AEMs very effectively. By controlling the feed molar ratio of reactants, cellulose AEMs (QC-1) having wide varieties of ion exchange capacity (0.63-1.54 mmol g^-1) and degree of substitution (0.52-1.39) were successfully prepared. QC-1 achieved one of the highest OH^- conductivity values (∼42.6 mS cm^-1) among reported cellulose-based AEMs. QC-1 sho
