红外光谱法在高分子研究中的应用极为广泛,这是由于它有很多优点。在实验技术上,红外分光光度计的结构比较简单,操作方便,而且对各种相态(气、液、固)的样品均适用,需要的样品量也较少(一般可在毫克数量级以下)。另一方面,红外光谱可以提供极为广泛的情报,它不仅可以区分不同化学结构的高聚物,而且也可以反映出高聚物物理结构的变化,如晶态和
Infrared spectroscopy in polymer research is extremely versatile due to its many advantages. In the experimental technique, the structure of infrared spectrophotometer is relatively simple, easy to operate, but also for a variety of phase (gas, liquid, solid) samples are applicable, the amount of samples required less (usually less than the order of milligram) . On the other hand, infrared spectroscopy can provide a very wide range of intelligence, it can not only distinguish between different chemical structure of the polymer, but also can reflect changes in the physical structure of the polymer, such as crystalline and
