Development of polymeric membranes based on quaternized polysulfones for AMFC applications
A Carbone, R Pedicini, I Gatto, A Saccà, A Patti, G Bella… - Polymers, 2020 - mdpi.com
A series of quaternary ammonium-functionalized polysulfones were successfully
synthesized using a chloromethylation two-step method. In particular, triethylammonium and
trimethylammonium polysulfone derivatives with different functionalization degrees from
60% to 150% were investigated. NMR spectroscopic techniques were used to determine the
degree of functionalization of the polymers. The possibility to predict the functionalization
degree by a reaction tool based on a linear regression was highlighted. Anionic membranes …
