摘要
Abstract
With chitosan as raw material, Ca/Zn-nano carboxymethyl chitosan complexing was pre-pared through carboxymethylation, nanocrystallization and complexing with Ca2+, Zn2+. The struc-ture 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 Ca2+ and Zn2+ are con-tained in Ca/Zn-nano carboxymethyl chitosan. Ca2+ and Zn2+ compound successfully with nano car-boxymethyl chitosan. The composite has lower crystallization, higher solubility, more uniform round morphology and significant shorter coagulation and hemostasis time. Compared with Zn-nano car-boxymethyl chitosan, Ca-nano carboxymethyl chitosan is possessed better structure and better prop-erties of coagulation and hemostasis.关键词
