Thermally Cured Sulfonated para‐PBI as Ion Solvating Membrane for Use in Water Electrolysis

Advanced Energy Materials, Volume 15, Issue 25, July 1, 2025.
The cMS‐PBI membrane is designed to be free of the known breaking points which limit the lifetime of membranes in alkaline electrolysis systems. As supported by high conductivity and 6 months ex situ stability test, the cMS‐PBI ion solvating membrane can substitute anion exchange membranes and thus can reduce the cost of green hydrogen by increasing ...

Improving Blood Compatibility of Polyethersulfone Hollow Fiber Membranes via Blending with Sulfonated Polyether Ether Ketone

Macromolecular Materials and Engineering, 2016
Appropriate membrane for blood contacting applications requires hemocompatibility and high permeation flux; it should inhibit proteins or platelets adsorption and still possess high permeability. Aiming to improve the polyethersulfone (PES) hollow fiber membrane hemocompatibility, sulfonated polyether ether ketone (SPEEK) is self‐synthesized in the ...
