PROTON-CONDUCTIVE RESIN COMPOSITION, ITS PREPARATION PROCESS AND PROTON-CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a proton-conductive resin composition which yields a proton-conductive film showing a high proton conductivity without increasing its acid concentration, its preparation process and the proton-conductive film formed from the composition.

SOLUTION: The composition comprises silica and a proton-conductive sulfonated polyarylene. In the process for preparing the composition, a powdery silica whose primary aggregate has an average particle size of ≤50nm is mixed with the sulfonated polyarylene.
