Sulfonated poly(ether ether ketone) (SPEEK) membranes were thermally treated at temperatures between 120 and 160 degrees C. Water uptake measured at different relative humidity values or by full immersion in water between 25 and 145 degrees C was found to depend very strongly on previous thermal treatment and casting solvent. Water-uptake coefficient values as low as 10-15 even upon immersion i...

Proton exchange membranes (PEM), which have been commonly used in fuel cells raised interest for the application harsh environments involving ionizing radiation. Therefore, radiation stability and ability to sustain their functionality under environment are of great interest. Within this study, electron beam irradiation dose range from 50 500kGy was evaluate effects on physico-chemical mechanic...
