| 摘 要： | 以过氧化苯甲酰(BPO)作引发剂,通过溶液接枝聚合法把苯乙烯接枝到原硅酸钠改性的聚偏氟乙烯(PVDF)膜上,磺化后得到聚偏氟乙烯接枝苯乙烯磺酸(PVDF-g-PSSA)电解质膜。研究发现,原硅酸钠改性的PVDF膜与苯乙烯发生接枝聚合反应,且接枝率与添加原硅酸钠的质量分数呈线性变化关系。用红外光谱检测原硅酸钠改性的PVDF膜经过接枝和磺化后所发生的结构变化,并用扫描电镜(SEM)观察PVDF膜接枝前后的形貌以及接枝磺化后产物PVDF-g-PSSA膜的形貌及硫和硅分布。研究表明,原硅酸钠改性的PVDF膜与苯乙烯进行接枝共聚反应时,PVDF膜结构在接枝前后和磺化前后发生变化,确认苯乙烯接枝到PVDF膜上。

| Abstract: | A new method based on a solution graft technique was used to prepare poly(vinylidene fluoride) grafted polystyrene sulfonated acid (PVDF-g-PSSA) proton exchange membrane. Polystyrene is easily grafted into PVDF doped plain sodium silicate (Na4SiO4). There is a linear relationship between the degree of grafting and the content of Na4SiO4. Fourier transform infrared spectroscopy was used to characterize changes of the membrane's microstructures after grafting and sulphonation. The morphology of the membrane's... |
