摘要：

为了提高聚乙烯亚胺（PEI）还原制备纳米银的能力，增加纳米银水溶液稳定性，采用化学接枝改性PEI，并探讨改性聚乙烯亚胺（MPEI）还原、控制纳米银生成的机制，实现对棉织物的抗菌整理。红外光谱分析结果表明，通过化学反应，成功将羧酸根离子和酰胺键引入PEI长链分子；X射线衍射、紫外可见光光谱和粒径测试结果表明，MPEI能高效还原制备纳米银，所制备的纳米银溶液在1个月内保持稳定；透射电子显微镜测试结果表明，MPEI制备的纳米银尺寸呈双峰分布，生成2nm左右的超小型纳米颗粒和10nm左右的纳米颗粒；在常温常压条件下，棉织物通过MPEI/纳米银溶液浸渍整理，得到的抗菌棉织物对大肠杆菌和金黄色葡萄球菌的抑菌率达到95%以上。

Abstract:

In order to improve the reduction capability of nano-silver by polyethyleneimine (PEI) and stabilize the nano-silver solution, a modification of PEI by chemical grafting was described in this paper. The mechanism of modified-polyethyleneimine (MPEI) was proposed, and its antibacterial application in finishing of cotton fabrics was studied. According to FT-IR, the carboxyl acid ion and the amide bond were introduced into PEI successfully by chemical reactions. XPS, UV-visible and particle size analysis showed that MPEI can not only can synthesize nano-silver efficiently, but also stabilize nano-silver solution for a month at least. TEM test indicated that nano-silver synthesized by MPEI contained ultra-small spherical nanoparticles with an average diameter of 2 nm and larger particles with a average diameter of 10 nm. Under conditions of room temperature and atmosphere pressure, the bacterial reduction rates of cotton fabrics treated with MPEI/nano-silver solution against Escherichia coli and Staphylococcus aureus reached 95%.
