Abstract:
High performance solid polymer electrolyte membranes (SPEM) were prepared from polyether ether ketone (PEEK) with high mechanical strength and thermal stability. The sulfonation reaction improved membrane hydrophilicity and water absorbility, and thus increased ionic conductivity for the applications in direct methanol fuel cells (DMFC). The incorporation of nano-SiO2 composites could be devoted to the thermal and mechanical properties, and methanol permeability. The supercritical carbon dioxide (scCO2) fluid treatment imposed a plasticizing effect by Lewis acid-base interaction between the CO2 and the electron donor species on polymer chain. The glass transition (Tg) and melting temperature (Tm) could be reduced.
