文摘

Phosphonic acid functionalized polysulfone (PSF-PA) and triazolyl functionalized polysulfone (PSF-Tri) are synthesized. Synergetic proton conducting effect is observed in PSF-PA/PSF-Tri acid-base composite membrane. The composite membrane shows reduced hydrophilicity, methanol permeability and improved tensile strength.
