Poly(vinyl alcohol)/poly(2-acrylamido-2-methyl-1-propanesulfonic acid (PAMPS)/3-glycidyloxypropyl)trimethoxysilane (PVA/PAMPS/GPTMS) organic/inorganic proton-conducting polymer membranes are prepared by a solution casting method. PAMPS is a polymeric acid commonly used as a primary proton donor, whi

Polybenzimidazole (PBI)/ionic liquid (IL) composite membranes were prepared from an organosoluble, fluorine-containing PBI with ionic liquid, 1-hexyl-3-methylimidazolium trifluoromethanesulfonate (HMI-Tf). PBI/HMI-Tf composite membranes with different HMI-Tf concentrations have been prepared. The io
## Abstract **Summary:** Novel poly(aryl ether sulfone) copolymers containing 2,5βbiphenylpyridine and tetramethyl biphenyl moieties were synthesized by polycondensation of 4βfluorophenyl sulfone with 2,5β(4β²,4β³ dihydroxy biphenyl)pyridine and tetramethyl biphenyl diol. Copolymers with different mo
