含氨基磺化聚芳醚酮砜质子交换膜的制备与性能
Preparation and Behavior of Sulfonated Poly (aryle ether ketone sulfone)Containing Amino Proton Exchange Membrane
摘要
Abstract
The sulfonated poly(aryle ether ketone sulfone) with different sulfonation degree containing amino copolymers were prepared by polycondensation method.The FTIR and 1 H NMR spectra of amino membranesulfonated poly(aryle ether ketone sulfone) (Am-SPAEKS) show that the amino groups are introduced into SPAEKS copolymers.The measured results show that the thermal stability,dimensional stability,resistance methanol performance and proton conductivities of Am-SPAEKS membranes are improved due to the introduction of amino groups.The proton conductivity of Am-SPAEKS-1 membrane reaches 0.0894 S/cm at 80 ℃.The methanol permeability coefficient of Am-SPAEKS-1 membrane is only 0.24×10-6 cm2/s,which is lower than that of pure SPAEKS(0.87×10-6 cm2/s) membrane and Nafion(2×10-6 cm2/s) membrane.All the results indicate that the Am-SPAEKS membranes are promising as proton exchange membranes for middle-high temperature proton exchange membrane fuel cells applications and direct methanol fuel cells(DMFCs).关键词
