Tri-quaternized poly (ether sulfone) anion exchange membranes with improved hydroxide conductivity

A novel guanidinium grafted poly(aryl ether sulfone) for high-performance hydroxide exchange membranes.

A novel poly(aryl ether sulfone) ionomer containing hexaalkylguanidinium groups was synthesized, and membranes formed from this polymer displayed large ionic clusters, high hydroxide conductivity, and excellent solubility in low boiling point water-soluble solvents such as ethanol and methanol.

Novel self-crosslinked poly(aryl ether sulfone) for high alkaline stable and fuel resistant alkaline anion exchange membranes.

Novel self-crosslinked alkaline anion exchange membranes with high alkaline stability, excellent dimensional stability and extraordinary methanol resistance were synthesized successfully without using any catalyst or a separate crosslinker.

Poly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review

Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...

PES/Quaternized-PES Blend Anion Exchange Membranes: Investigation of Polymer Compatibility and Properties of the Blend

Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...
