摘要:
以羧甲基壳聚糖（CMCS）为原料，经氧化后得到双醛羧甲基壳聚糖（DAC），将DAC与氨基化二氧化硅（SiO2-NH2）进行杂化反应得到DAC-SiO2杂化材料，用作胶原的交联改性剂。研究结果表明，不同杂化程度的DAC-SiO2改性剂均不会破坏天然胶原的三股螺旋结构；与DAC-SiO2杂化材料反应后，胶原的热稳定性提高，但当SiO2-NH2与DAC质量比超过1/5时，提高程度略有下降。
Abstract:
Carboxymethyl chitosan was oxidized to obtain dialdehyde carboxymethyl chitosan (DAC), and then DAC was reacted with SiO2-NH2?to get a hybrid material (DAC-SiO2) which was used as a modifying agent for collagen. The studying results indicated that the triple helix structure of native collagen was not destroyed by all kinds of DAC-SiO2, and the thermal stability of collagen was improved after reacting with DAC-SiO2, but the improvement slightly weakened while the weight ratio of SiO2-NH2?and DAC was no less than 1/5.
