摘要

采用溶胶-凝胶原位合成技术制备了SiO2/聚2-丙烯酰胺- 2-甲基丙烷磺酸(PAMPS)改性聚乙烯醇(PVA)电解质膜。利用傅里叶变换红外光谱对接枝后膜的微观结构变化进行了表征。利用扫描电显微镜和x射线衍射对膜的微观结构进行了研究。结果表明:SiO2 (30wt%)/PVA- pamps (20wt%)膜的电导率为4.12×10-2S/cm, AMPS易于与名称型二氧化硅改性的聚乙烯醇(PVA)混合;

Structure and morphology of SiO2/PVA-PAMPS composite membrane

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.
