摘要

Novel composite membranes were prepared from sulfonated poly (ether ether ketone) (SPEEK), containing phosphotungstic acid (PTA) and silica generated by the hydrolysis of tetraethyl orthosilicate. PW₁₂O₄₀^3- anion presents PTA/SiO₂/SPEEK composite membranes in a Keggin structure, and PTA and SiO₂ are amorphously distributed in the composite membranes. The composite membranes have good proton conductivity and low methanol permeability, and enhanced stability in phosphotungstic acid.
