| 摘 要： | 将钠基膨润土(Na-MMT)掺入磷钼酸/聚乙烯基吡咯烷酮(PMA/PVP)体系中,利用透射电子显微镜(TEM)、原子力显微镜(AFM)、红外光谱(FTIR)、热重-差热(TG-DTA)、紫外-可见吸收光谱(UV-Vis)、X射线光电子能谱(XPS)等手段对复合薄膜的结构、热稳定性和光致变色性能进行了研究.红外光谱结果表明keggin结构磷钼酸和聚乙烯吡咯烷酮的基本结构在复合膜中仍然存在,复合膜中高分子与质子结合,以阳离子的形式与杂多阴离子成盐.Na-MMT的掺杂未对复合膜中PVP和PMA间的相互作用产生影响,但其掺杂提高了复合膜的热稳定性.在紫外光照下,复合膜由无色变为蓝色,杂多酸被还原产生杂多蓝.Na-MMT的掺杂降低了复合膜的光致变色响应性,这是由于多酸分子与钠基膨润土之间发生阳离子交换作用导致的.

| Abstract: | The phosphomolybdic acid/polyvinylpyrrolidone(PMA/PVP) nanocomposite films doped with sodium-bentonite(Na-MMT) were been prepared.The structure,thermal stability and photochromic behavior of these composite films were studied with TEM,AFM,FTIR,TG-DTA UV-Vis and XPS analysis.FTIR results showed the Keggin geometry of PMA and the structure of PVP were still preserved in the PMA/PVP composite films,and the salts were formed by combination of the ions based on the N atoms in the polymeric molecules and H~+ of t... |
