| 摘 要： | 采用热重分析(TG)研究壳聚糖季铵盐铜配合物在30℃～600℃的温度范围内的热降解行为,探讨壳聚糖季铵盐铜配合物的热稳定性。研究结果表明:壳聚糖季铵盐铜配合物的热降解为一步反应,取代度对壳聚糖季铵盐的热降解有明显的影响,壳聚糖季铵盐铜配合物的特征降解温度都随取代度的增加而降低。

| Abstract: | The thermal degradation of quaternary gravimetry analysis（TG） in the temperature range 30℃ chitosan -cupric composition in nitrogen was studied by thermo- 600℃. The thermal stability of hydroxypropyl trimethyl ammoni- um chloride chitosan - cupric ion compounds was discussed. The results showed that the thermal degradation of quaternary ehitosan - cupric composition was a one - stage reaction. The impact of degree of substitution on the thermal degradation of quaternized chitosan was significant, and the characteristic temperatures of the degradation were declined with the increase of degree of substitution. |
