静电纺丝制备含银纳米微粒的聚氧化乙烯纳米纤维

Preparation of Poly(ethylene oxide) Nanofibers Containing Silver Nanoparticles by Electrospinning

利用N,N-二甲基甲酰胺作为聚氧化乙烯的溶剂,同时也作为银离子的还原剂,将聚氧化乙烯溶液中的银离子还原成银纳米微粒,然后通过静电纺丝法成功地制备出了含银纳米微粒的聚氧化乙烯纳米纤维,并利用扫描电镜和透射电镜表征了含银纳米微粒的聚氧化乙烯纳米纤维。

In this article, N,N-dimethylformamide （DMF） was used as a solvent for the poly（ethylene oxide） as well as a reducing agent for the Ag＋ ions in the poly（ethylene oxide） （PEO） solutions. The Ag＋ ions in the PEO solution Were directly reduced to produce Ag nanoparticles by DMF and the resulting solution was electrospun into PEO nanofibers containing Ag nanoparticles. PEO nanoflbers containing Ag nanoparticles were observed by using the scanning electron microscope （SEM） and the transmission electron microscoov （TEM）.
