Sulfonated Polyphenylquinoxalines: Synthesis, Thermal Stability, and Proton Conductivity

摘要

A brief analysis of the publications on the synthesis of polyphenylquinoxalines, their sulfonation, and the study of their thermal stability and proton conductivity is presented. Polyphenylquinoxaline is synthesized based on 3,3',4,4'-tetraaminodiphenyl oxide and 1,4-bis(phenylglyoxalyl) benzene and sulfonated. Films of sulfonated polyphenylquinoxaline with sulfur contents of 0.6, 1.7, 6.0, and 8.0% are obtained, and their thermal stability, proton conductivity, and testing as a proton-conducting membrane in a membrane electrode block of a fuel cell are investigated.
