摘要: 运用全反射红外技术对逐层组装的含重氮高分子薄膜进行了分步定量分析.利用-CH2-峰的逐层变化规律,确认了在组装过程中每层吸附高分子的量是一致的.通过重氮基-N≡N+特征的吸收峰,定量计算了在特定实验条件下,-N≡N+分解生成共价键的比例.这些结果为认识重氮高分子薄膜的生长提供了更为直接和细致的信息.

Abstract: Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) has been successfully applied to quantifying analysis on layer-by-layer assembled macromolecular films containing diazo-resins. From the changes of -CH2-peaks,uniform adsorption of each single layer of macromolecules has been identified. We calculated the ratio of the decomposited -N≡N+ groups which form covalent bond to all -N≡N+ groups from the characteristic -N≡N+ absorption peaks. The results have provided direct and detailed information on the assembling process.
