It is an important problem that fabricating nano-filter materials with good adsorption and antibacterial properties in the application of nano-fiber membranes in the field of filtration. Among the preparation methods of various fiber and film materials

the electrospinning method has the characteristics of large specific surface area and high porosity

which provides an effective idea for preparing nano-filter materials with adsorption and antibacterial properties. In this study

the nano-silver particles-activated carbon (AgNPs-AC) composite nanofiber membrane was prepared by the electrostatic spinning method

and nano-silver particles were deposited on the activated carbon carrier so that a highperformance filter electrospun composite fiber membrane with good antibacterial adsorption can be prepared. The morphology and structure of the composite nanofibers were characterized by scanning electron microscopy (SEM)

X-ray diffraction (XRD) and other equipments. Besides

the adsorption performance and antibacterial properties of the composite fiber membrane were investigated. The results show that the fiber diameter distribution of the prepared AgNPs-AC composite nanofiber membrane gradually tends to be uniform with the increase of activated carbon and silver concentration. Moreover

when the EVOH mass fraction is 10% and the silver nitrate/activated carbon concentration ratio is 0.05/0.085 (g/mL)

the composite fiber membrane possesses the best adsorption performance. In addition

the AgNPs-AC composite nanofiber membrane shows good antibacterial properties against Staphylococcus aureus.
