Synthesis of polymers containing perfluoroalkyl sulfonated side chains for proton conductivity membranes

Abstract : As part of this work, the objective was to develop aromatic polymers with proton conduction properties. To achieve this, the sulfonic acid motifs were introduced along the macromolecular chains. The methodology of synthesis of these polymers was to polymerise the precursor containing in their structure a perfluoroalkyl sulfone moieties. Four novel precursors have been initially synthesized. Different aromatic polymers were prepared from these precursors by varying the rate of perfluoroalkyl sulfonated sequences. These polymers were then used in the form of dense membranes obtained by a casting process of evaporation. From these membranes, swelling studies in water and ionic conductivity were carried out.
