| 摘 要： | 研究了在微波辐射的条件下采用戊二醛对壳聚糖进行交联，通过红外光谱等方法对交联前后成膜性能进行了研究，并与水浴加热制得的交联壳聚糖进行了对比.实验结果表明，微波交联比水浴加热迅速且均匀，分析了交联剂用量、反应时间及加热功率对膜的吸水率的影响;另外，对所成膜拉伸强度、断裂伸长率受交联反应过程各因素影响变化的规律进行了研究.

| Abstract: | The chitosan crosslinked under microwave irradiation with glutaraldehyde was studied.The performance of its film was determined by FT-IR et al,and compared with chitosan crosslinked under water-bathing.Results show that the reaction of chitosan crosslinked under microwave irradiation is faster than that under water-bathing which finished in only 2 min~3 min.The water-absorbability of chitosan crosslinked under irradiation is higher than that under water-bathing with the same dosage of glutaraldehyde.The tensile strength and break tensile rate of chitosan crosslinked under irradiation is better than that under water-bating when it reacted in low power and short time in micro-oven. |
