This research has successfully fabricated Ag nanoparticles and PVA/Ag nanofiber as antibacterial agents. The silver nanoparticles were synthesized using a chemical reduction method, while PVA/Ag nanofiber was successfully fabricated with silver nanoparticles and PVA polymer materials using electrospinning method. The chemical reduction method is an effective method for obtaining nanometer-sized silver particles, while electrospinning is one of the most efficient and inexpensive methods to produce nanofiber products. The silver nanoparticles and PVA/Ag nanofiber were characterized using instruments of XRD, SEM, EDX, and antimicrobial test for PVA/Ag nanofiber. In addition, through an X-ray diffraction characterization, the average size of silver nanoparticles was approximately 19.12 nm. Meanwhile, the SEM morphological analysis of PVA/Ag nanofiber has an average fiber diameter of 449.11 nm. The result of EDX analysis of PVA/Ag nanofiber showed the aggregation of silver nanoparticles in the range of polymer fibers shown by white clumps. In addition, the antibacterial test results on PVA/Ag nanofiber within 24 hours of incubation showed that the largest nanofiber zone of inhibition was in the diameter range of 0.9 cm. This case shows that PVA/Ag nanofiber has a relatively low antimicrobial power. This condition can be increased by reducing the possible impact of contamination from PVA/Ag nanofiber by the surrounding environment. Thus, the PVA/Ag nanofiber resulted in this study has a potential to be used as a wound dressing under optimal conditions. © Published under licence by IOP Publishing Ltd.
