摘要
采用三元共聚法制备了苯胺齐聚物为侧链的接枝型聚酰胺酸.通过红外光谱、核磁共振谱及高效凝胶渗透色谱等技术对聚合物结构进行了表征.该材料亚胺化后具有十分优异的热稳定性.紫外-可见光谱和电化学测试结果表明,该聚合物具有独特的光谱性质和可逆的电化学活性.聚酰胺酸/ITO电致变色电极具有颜色变化明显,响应速度较快,着色效率高等优点,是一种综合性能较好的电致变色聚合物材料.
A novel poly(amic acid) bearing oligoaniline pendants was designed and prepared. Fourier transform infrared spectroscopy(FTIR), 1H nuclear magnetic resonance spectroscopy(1H NMR) and gel permeation chromatography(GPC) were used to characterize its structure. The prepared polymer displayed an interesting spectroscopic property and reversible electrochemical activity. The material shows satisfactory electrochromic properties with high contrast value, acceptable switching times and excellent coloration efficiency.
