【摘要】 采用浓硫酸作为磺化剂磺化聚醚醚酮,制备具有不同磺化度的磺化聚醚醚酮质子交换膜。实验结果表明,磺化聚醚醚酮质子交换膜具有理想的质子电导率和机械强度。当磺化度为86％(离子交换当量为2．48 meq/g) 时,磺化聚醚醚酮质子交换膜的电导率为5．5×10-3 S／cm;磺化聚醚醚酮质子交换膜的拉伸强度为45．9 MPa。更多还原

【Abstract】 Sulfonated poly(ether ether ketone) (SPEEK) membranes with various degrees of sulfonation (DS) were prepared with H2SO4 as sulfonating agent. It was found that the SPEEK membranes have promising mechanical strength and perfect proton conductivity. For 86% DS, proton conductivity was 5. 5×10-3 S/cm; and the max mechanical strength was 45.9 MPa.更多还原
