Understanding ion diffusion in anion exchange membranes; effects of morphology and mobility of pendant cationic groups
Mohammad Rezayani, Farhad Sharif, Hesam Makki
Abstract
A new methodology to assess ion diffusion in side-chain modified AEMs reveals separate roles for functionality and side-chain length: the former determines hydrophilic pathway morphology and the latter regulates anion diffusion rate in the channels.
