Abstract

TiO2 nanofiber with different diameters was synthesized by calcining electrospun polyacrylonitrile (PAN) nanofibers embedded with titanium precursors. The TiO2 nanofibers was incorporated into sulfonated poly(ether ether ketone) (SPEEK) to preprare the proton exchange membrane (PEM). The incorporation of inorganic nanofiber can improve the performance of composite membrane. The conductivity of the SPEEK/TiO2-130 composite membrane is 1.15 times higher than that of the pristine SPEEK membrane at 100% relative humidity and 25 °C. In addition, the stable fiber skeleton suppresses the swelling coefficient of PEM. Compared to pristine SPEEK membrane, the SPEEK/TiO2 membranes exhibit higher comprehensive performance.
