| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 96 === A series of crosslinkable sulfonated poly(ether ketone)s containing norbornene groups were synthesized by aromatic nucleophilic substitution reaction . To decrease the swelling of fuel cell membranes , crosslinking of theses polymers by radical polymerization were be tested. These polymers had good thermal and oxidative stability , and good dimensional stability in hot water . The proton conductivity of NB-Np SPEEKK at room temperature is 7.52 x 10-2 S/cm. The results showed these materials containing norbornene groups are possible inexpensive candidate materials for proton exchange membranes in fuel cell applications.
