The physicochemical characterisation of a CMX membrane in hydro-organic media was undertaken. N-Methylformamide (NMF) and five other solvents with various relative permittivities were investigated. The water content, electrical resistance and transpo

The presence of an organic solvent often modifies the transport properties of an ion exchange membrane. Compared to ethylene glycol (EG) and N-methylformamide (NMF), tetrahydrofuran (THF) has a particular behavior in a Nafion perfluorosulfonic membra
