Abstract :
Polyvinyl alcohol(PVA) modified by SiO2/poly 2-acrylamido 2-methylpropane sulfonic acid (PAMPS) electrolyte membrane SiO2/PVA-PAMPS was prepared by a Sol-gel synthesis in situ technique. Fourier transform infrared spectroscopy is used to characterize changes of the membrane´s microstructures after grafting. The morphology of the membrane´s microstructures are studied by scanning electrolytic microscope and X-ray diffraction. The results show that the conductivity of the SiO2 (30wt%)/PVA-PAMPS(20wt%) membrane was 4.12×10-2S/cm and AMPS is easily blended into polyvinyl alcohol (PVA) modified by namometer silicon dioxide.
