Abstract

Abstract:

To prepare sulfonated polyether ketone/barium titanate(SPAEK/BT) hybrid membrane, the mixture containing BT suspension in cyclohexane obtained under ultrasonic condition and dimethyl sulfoxide solution of SPAEK was casted onto the glass plates. The uniform dispersion of BT 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. Compared to blank membrane, the anti-swelling, thermal stability, and oxidative stability of hybrid membranes are improved respectively. The water stability and mechanical properties are also improved, whereas the proton conductivity of the hybrid membrane is decreased in some extent.

Key words: barium titanate, sulfonated polyether ketone, proton exchange membrane
