摘要

采用季铵化反应合成了一种新型季铵盐

并通过缩合反应制备了一种水溶性壳聚糖;通过静电层层自组装的形式制备了具有抗菌、止血功能的棉织物。采用扫描电子显微镜及傅里叶红外光谱仪对棉织物样品的表面形态和化学结构进行分析。研究发现

经自组装整理后

原棉织物的经向及纬向断裂强力保留率约为70%;样品仍具备一定的强力性能。水溶性壳聚糖极大地提升了原棉织物的止血性能

凝血指数(BCI)从75±8降低至25±4;自组装织物可在60 min内杀死81.08%和73.21%数量级为6.57和6.45的金黄色葡萄球菌和大肠杆菌O157∶H7

且抗菌性能随着组装层数的增加而不断提升。

Abstract

In this work

one kind of novel quaternary ammonium salt was synthesized

and used to prepare the watersoluble chitosan (CS38)

via

condensation reaction. Layer-by-layer self-assembly process were used to prepare the antimicrobial and hemostatic cotton fabric. The physical and chemical structures of the modified cotton fabric were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). It was found that the warp and weft breaking force retention rate of modified cotton was about 70%. The sample still showed good breaking force properties even after modification. The addition of water-soluble chitosan enhanced the hemostatic and antimicrobial properties of original cotton significantly. The blooding clotting index (BCI) of modified sample was decreased from 75±8 to 25±4. This modified cotton fabric expressed good antimicrobial properties and inactivated 81.08% and 73.21% of

E. coli

O157∶H7 and

S. aureus

with 6.57 and 6.45 logs reductions within 60 min of contact

respectively. The antimicrobial properties of modified sample were increased significantly with the addition of self-assembly layers.
