Preparation and properties of cross-linked sulfonated poly(arylene ether sulfone)/sulfonated polyimide blend membranes for fuel cell application

Fluorenyl‐containing Quaternary Ammonium Poly(arylene ether sulfone)s for Anion Exchange Membrane Applications

“…For instance, the membrane of QA‐bPAES(20/10)‐1.26 exhibited dimensional change of 3.3% and 4.3% in the in‐plane and through‐plane direction at 30 °C, 4.8% and 6.1% at 60 °C, and 6.3% and 7.1% at 80 °C, respectively. The swelling behavior was quite different from their cationic analogues, the sulfonated ones which was highly anisotropic 39. The relationship between membrane swelling, IECs and chemical structure showed the same trend as that for water uptakes.…”

Building bridges: Crosslinking of sulfonated aromatic polymers—A review

“…The hydrogen/ air fuel cell performance was superior to that of commercial Nafion 212 and no performance degradation was observed in the in-situ PEMFC durability test for 2 days [156]. However, it was considered that this type of crosslinked SAP usually encountered phase separation and poor compatibility [157]. Some attempts were made to resolve this problem [158][159][160].…”

Facile synthesis of new thermally stable and organo-soluble polyamide-imides from phosphorus-containing aromatic amines and various dianhydrides

“…They are well known for their superior resistance to spontaneous pyrolysis and oxidative degradation [5,6]. Therefore, they are used as adhesives, film forming materials, composite matrices, coatings, membranes, and in aerospace, transportation, microelectronics, fuel cell, optoelectronics, etc., in severe environments [7][8][9][10]. However, their insoluble nature in most organic solvents and their high softening and glass transition temperatures (T g ) make these systems difficult to process and fabricate [11].…”
