摘要/Abstract

摘要： 采用静电纺丝技术, 以N,N-二甲基甲酰胺为溶剂, 聚丙烯腈为载体, 制备复合纳米纤维聚丙烯腈/纳米纤维素晶体/银, 并用Fourier变换红外光谱（FT-IR）、透射电子显微镜（TEM）、扫描电子显微镜（SEM）、差热热重分析（TG-DTG）和X射线衍射（XRD）等方法对复合纳米纤维的化学结构、形貌、热稳定性和晶体结构进行表征. 结果表明：聚丙烯腈、纳米纤维素晶体和银纳米粒子有机结合形成复合纳米纤维聚丙烯腈/纳米纤维素晶体/银；复合纳米纤维的尺寸均匀, 平均直径为（214±12）nm, Ag纳米粒子在复合纳米纤维体系中均匀分布, 粒径为5~25 nm；该复合纳米纤维对金黄色葡萄球菌和大肠杆菌的抗菌性能优异.

Abstract: Using electrospinning technology, N,Ndimethylformamide as solvent and polyacrylonitrile (PAN) as carrier, we prepared PAN/CNC/Ag composite nanofibers. The chemical structure, morphology, thermal stability and crystal structure of composite nanofibers were characterized by Fourier transform infrared spectroscopy (FT-IR), transmission electromicroscopy (TEM), scanning electron microscope (SEM), thermal gravity differential thermal gravity analysis (TG\|DTG) and X-ray diffraction (XRD). The results show that PNC,CNC and Ag nanoparticles combined form PNC/CNC/Ag composite nanofibers. The composite nanofibers are uniform in size with average diameter of (214±12)nm, and the Ag nanoparticles are uniformly distrib
uted in the composite nanofibers with particle size of 5—25 nm. The composite nanofibers have excellent antimicrobial properties against grampositive Staphylococcus aureus (S.aureus) and gramnegative Escherichia coli (E.coli).
