Abstract
Novel membrane composites were prepared from polyvinyl alcohol) (PVA), poly(acrylic acid) (PAA) and sulfonated non-woven PP/PE (s-PP/PE) filament sheet to improve the chemical stability and mechanical properties of alkaline solid polymer electrolytes (SPE). The ionic conductivity of the PVA/PAA/s-PP/PE membrane composite was about 0.08-0.21 S cm-1 at room temperature when the polymer electrolyte matrix had the blend ratio of PVA/PAA at 10/3-10/7.5. The characteristic properties of these membrane composites were investigated using DSC, SEM, XRD, stress-strain test and AC impedance spectroscopy. Experimental results showed that the PVA/PAA/s-PP/PE membrane composites exhibited excellent mechanical strength and electrochemical stability. Further development would help to meet the design requirements for the energy storage system and other electrochemical devices.
