Synthesis and characterization of poly(arylene ether ketone)with sulfonated fluorene pendants for proton exchange membrane

Material type: TextSeries: ; Journal of Membrane Science, 297(1-2), p.90-97, 2007Contained works:
  • Shang, X
  • Fang, S
  • Meng, Y
Subject(s): Online resources: Abstract: Novel poly(arylene ether ketone)with fluorene pendants were synthesized and then sulfonated into a series of poly(arylene ether ketone)s with sulfonated fluorene pendants using chlorosulfonic acid. The sulfonated polymers were thereafter cast into membranes from their solutions. The properties of the ionic exchange capacity, sulfonation degree,water uptake, mechanical properties, thermal and oxidative stabilities as well as proton conductivities of the membranes were fully investigated. It was found that their proton conductivities increased continuously with increasing testing temperature up to 130 .C at 100
