Abstract

Modified electrospinning apparatus has been developed for continually fabricating nanofiber-coated microfibers. Two positively charged spinnerets were introduced and the PVA microfibers containing silver nanowires (AgNWs) were acted as the grounded collector. The prepared PVA/AgNWs microfiber moved through the electric field during electrospinning process and the nanofibers deposited onto the surface of the PVA/AgNWs microfiber to form a coating layer. Due to the addition of AgNWs, the micro/nano composite fibers had antimicrobial activity against Escherichia coli (ATCC 8099) and Staphylococcus aureus (ATCC 6538). In addition, the human osteoblasts attached well on the micro/nano composite fibers in a 3D direction.
