摘要

以壳聚糖为原料，经羧甲基化、纳米化与Ca

、Zn

复合制备出纳米羧甲基壳聚糖含钙、锌复合物，采用红外光谱、X射线衍射光谱、扫描电镜等光学手段对样品进行结构表征，考察了复合物的凝血、止血性能。结果表明：纳米羧甲基壳聚糖结构中含有磷酸盐结构，Ca/Zn-纳米羧甲基壳聚糖结构中含有Ca

与Zn

，Ca

和Zn

与纳米羧甲基壳聚糖成功复合；复合物的结晶性下降、溶解性提高、形貌均匀圆整，且凝血、止血时间明显缩短；Ca-纳米羧甲基壳聚糖比Zn-纳米羧甲基壳聚糖结构更稳定，凝血、止血效果更好。

Abstract

With chitosan as raw material

Ca/Zn-nano carboxymethyl chitosan complexing was prepared through carboxymethylation

nanocrystallization and complexing with Ca

. The structure was characterized by infrared spectroscopy

X-ray diffraction spectroscopy and scanning electron microscopy. The properties of coagulation and hemostatic were investigated. The results show that the polyphosphate structure is contained in nano carboxymethyl chitosan

as Ca

and Zn

are contained in Ca/Zn-nano carboxymethyl chitosan. Ca

and Zn

compound successfully with nano carboxymethyl chitosan. The composite has lower crystallization

higher solubility

more uniform round morphology and significant shorter coagulation and hemostasis time. Compared with Zn-nano carboxymethyl chitosan

Ca-nano carboxymethyl chitosan is possessed better structure and better properties of coagulation and hemostasis.
