| 摘 要： | 利用傅里叶变换红外光谱仪测定了升降温过程中聚酰胺56(PA56)的系列红外光谱,考察了PA56红外光谱中酰胺Ⅰ带、酰胺Ⅱ带及N—H伸缩振动谱带随温度变化的情况,分析了温度对PA56氢键的影响。研究发现,随着温度的升高,氢键键合羰基与氨基的红外吸收谱带的峰强逐渐减小,而游离羰基、氨基的红外吸收谱带的峰强缓慢增大。由此表明PA56的氢键密度随着温度的升高而降低。

| Abstract: | The infrared spectrum of polyamide 56(PA56)in both heating and cooling process were scanned by Fourier transform infrared spectrum(FTIR).The amide I,amide II and N—H stretching vibration bands with the change of temperature were examined and the effect of temperature on the hydrogen bond of PA56 was analyzed.It was found that the peak intensity of infrared absorption band of the hydrogen bonded carbonyl and amine groups decreased with the increase of temperature,while the peak intensity of infrared absorption band of the free carbonyl and amine groups increased slowly.The results suggest that the density of the hydrogen bond in PA56 decreases with the increase of temperature. |
