Tuning of hydrophobic side-chain poly(styrene-ethylene-co-butylene-styrene) tri-block copolymer: a comparative studies of free-volume effect on anion exchange membranes
There is a great importance in the development of anion exchange membrane fuel cells (AEMFCs) for renewable energy research. The high conductivity and alkaline stability under high pH conditions at elevated temperatures are required for AEMs. We report herein SEBS-based AEMS with different hydrophobic side chain lengths, and investigated the properties of the corresponding AEMs, including conductivity, morphology and chemophysical stabilities.
