摘要

通过两锅法成功制得纳米银/聚多巴胺/纤维素纤维(nanoAg/PDA/CF)抗菌纸,此过程无需外加还原剂。扫描电镜(SEM)观察及能谱(EDX)分析表明,抗菌纸表面载有尺寸为70~150 nm球形或立方形纳米银粒子。X射线衍射(XRD)和热重(TGA)分析证明,纳米银粒子原位生成并沉积在聚多巴胺功能化的纤维素纤维表面。所制得的nanoAg/PDA/CF新型抗菌纸对金黄色葡萄球菌(Staphylococcus aureus)和大肠杆菌(Escherichia coli)均表现出显著的抗菌活性。nanoAg/PDA/CF复合纤维的最佳制备条件为:pH值8.5,多巴胺质量浓度125 mg/L,硝酸银质量浓度375 mg/L,多巴胺自聚合时间2 h,室温。

Abstract

The nano silver/polydopamine/cellulose fiber(nanoAg/PDA/CF) antibacterial paper is successfully in situ prepared by the twopot method without using any additional reducing agent. The scanning electron microscopy(SEM) and the energy dispersive X-ray spectroscopy(EDX) analyses reveal that the spherical or cuboidal silver nanopartiles with the size of 70~150 nm are loaded on the surface of the nanoAg/PDA/CF antibacterial paper. The X-ray diffraction(XRD) and the thermogravimetric(TG) analyses confirm that the silver nanopartiles are in situ generated and deposited on the polydopamine functionalized cellulose fiber surface. The novel nanoAg/PDA/CF antibacterial paper shows a remarkable antibacterial feature against both S. aureus and E. coli. The optimum preparative conditions of the nanoAg/PDA/CF composite are: the pH value of 8.5, the dopamine concentration of 125 mg/L, the silver nitrate concentration of 375 mg/L, the dopamine self-polymerization time of 2 h, and the room temperature.
