- Abstract
- In this work dense polymer electrolyte membranes (PEM) were prepared by casting and solvent evaporation from
homogeneous solutions of the sulfonated derivative of an amorphous polyetheretherketone, known as SPEEK-WC. In
order to obtain stabilized PEMs, the SPEEK-WC membranes were modified by following three different strategies: thermal
annealing, chemical cross-linking with a diamine and blending with Nafion ionomer. Various ex situ characterizations
were carried out on the modified and reference SPEEK-WC membranes, including: ion exchange capacity,
proton conductivity, liquid water uptake, counter elastic
index, chemical resistance in oxidative conditions, and gas
permeability. The results indicated that the first two methodologies
are able to increase hydrolytic and oxidative stability
of the SPEEK-WC membranes at a temperature higher
than 100 °C. (literal)
