Abstract:

Sulfonated poly(ether ether ketone ketone)(SPEEKK) membranes with different degrees of sulfonation(DS) were successfully prepared via electrospinning method. The morphology of the resulted membranes varies from nanospheres to nanofibers with increasing the concentration of SPEEKK. The conductivities of the membranes prepared  under the same condition increase with the DS increasing. The spherical morphological membranes with a DS of 1.2 show the highest proton conductivity, 0.55 S/cm, which is much higher than those of the membranes prepared via normal solution evaporation method. The results show that electrospinning is an efficient method to prepare high performance SPEEKK membranes with different morphologies.
