主　　题：SPEEK Proton exchange membrane Ionic liquids Conductivity 

摘      要：The membranes of sulfonated poly(etheretherketone) with 65% sulfonation degree were prepared by doping of Y2O3 and ionic liquids,such as 1-ethyl-3-methylimidazole tetrafluoroborate(EB) or 1-butyl-3-methylimidazole methanesulfonate(BS),*** the properties,including conductivities,water uptake,thermal stability and mechanical properties,of pure SPEEK based proton exchange membrane and SPEEK based proton exchange membranes by doping of ionic liquids and Y2O3 have been studied in the present *** experimental results showed that the conductivity of membranes increased with the temperature increased from 30 to 90 1C,except for that of pure SPEEK membrane increased with increasing temperature from 30 to 70 1C and decreased with increasing temperature from 70 to 90 *** conductivities of SPEEK/EB/Y2O3 and SPEEK/BS/Y2O3 composite membranes at 90 1C were 9.04 10 2 S cm 1 and 1.18 10 1 S cm 1 at 100% relative humidity(RH) and 8.04 10 2 S cm 1 and 1.02 10 1 S cm 1 at 50%RH,*** has been also found that the water uptake and thermal stability of the membranes slightly improved by doping of ionic liquids and *** tensile stress at break at room temperature was 2.61 MPa and 2.33 MPa,for SPEEK/EB/Y2O3 and SPEEK/BS/Y2O3,*** it may be considered that the modification with ionic liquids and Y2O3 is a good potential method for improving the properties of SPEEK proton exchange membrane.
