几种医用甲壳素无纺布的红外光谱分析和应用性能比较

文章研究了三种医用甲壳素无纺布的红外光谱和应用性能，结果表明：透射法所得红外光谱吸收峰扁平，不适合甲壳素无纺布的分析；红外反射法不需特别制样，分析在900-1700cm^-1和2800～3600cm^-1处出现了明显和较尖锐的吸收峰，分析方法完全可行：木纤维在1108．9cm。比甲壳素多一个峰，甲壳索在1264．8cm^-1、1587．7cm^-1和1658．2cm。处的峰强度大于木纤维；甲壳素／木纤维复合无纺布在创面模拟中没有出现粘连，手感柔软，颜色较白，更适合医疗敷料用途。

Infrared Spectroscopy and Application Performance Comparison of Several Medical Chitin Non-woven

Infrared spectra and application performance of three medical chitin non-woven was studied. The results showed that infrared absorption peak of non-woven with chitin base was flat, which showed the transmittance method was not suitable for the analysis of chitin non-woven. However, clear and sharp peaks of chitin non-woven were observed in 900-1700 cm^-1 and 2800-3600 cm^-1 without special preparation by reflection method. There were some difference between wood fiber and chitin that reflection peak could be observed at 1108.9 cm^-1 for wood fiber, while peak intensity of chitin were stronger than that of wood fiber at 1264.8 cm^-1, 1587.7 cm^-1 and 1658.2 cm^-1. Composite non-woven fabric with chitin and wood fiber was characterized with no adhesive, softer and whiter, which was more suitable for medical dressing use.
