AgNP-AC Composite Fibers and its Adsorption and Antibacterial Properties

In this study, the electrospinning method was used to prepare silver nanoparticle–activated carbon (AgNP-AC) composite nanofiber membranes, aiming obtain a high-performance dual-functional filter fiber membrane with good antibacterial and adsorption properties. A scanning electron microscope (SEM), X-ray diffractometer (XRD), other instruments were characterize morphology structure of nanofibers. The effects different concentrations activated carbon, silver, polymer (polyethylene–vinyl alcohol—EVOH) on discussed. performance investigated verify mutual influence carbon. results show that increase in concentration, diameter AgNP-AC distribution tends become uniform. When mass fraction EVOH is 10% concentration ratio nitrate 0.05 0.085 (g/ml), at best an rate 94.07%. also demonstrates function against Staphylococcus aureus most effective first 8 h. However, it found proportional ability, but has certain inhibitory effect
