To prepare sulfonated polyimide/ordered mesoporous carbon (SPI/CMK) hybrid membrane, the mixture, containing CMK suspension in ethanol obtained under ultrasonic condition and m-cresol solution of SPI, was casted onto the glass plates. The uniform dispersion of CMK in the hybrid membrane was confirmed via SEM. The properties of the corresponding hybrid membranes, such as water uptake, solvent uptake, size change, proton conductivity, methanol permeability, mechanical properties, and stabilities, were investigated. The results showed that, compared to the blank membrane, the anti-swelling, thermal stability, and oxidative stability of the hybrid membranes were improved by 15~30%, 20~30 oC, 1.3~1.5 times, respectively, the water stability and mechanical properties were also improved, whereas the proton conductivity of the hybrid membrane was decreased in some extent.
