Abstract:
The results of investigations in the field of electrolytic proton-conducting membranes based on aromatic condensation polymers are analysed and summarised. Primary attention is paid to characteristics of the starting polymer such as thermal stability, water absorption and proton conductivity. General approaches to the preparation of aromatic condensation polymers with high proton conductivity are considered, which include sulfonation, synthesis on the basis of monomers containing sulfonic groups, incorporation of sulfoalkylated substituents and the formation of acid-basic polymer complexes.
