Electrospun PVA Nanofibrous Membranes Reinforced with Silver Nanoparticles Impregnated Cellulosic Fibers: Morphology and Antibacterial Property

To enhance the mechanical and antibacterial properties of silver nanoparticle impregnated cellulosic fibers, carboxy-cellulose nanocrystals(CCNs) were grafted with chitooligosaccharide(COS), which was used as a stabilizer for nanoparticles (AgNPs). Nanofibrous membranes reinforced fibers(CCN-COS-AgNP) prepared via electrospinning using polyvinyl alcohol(PVA) matrix. The effects CCN-COS-AgNP contents on morphology, surface composition, properties, performances CCN-COS-AgNP/PVA examined. addition certainly improved PVA nanofibers. tensile strength significantly increased from 4.40 MPa to 8.60 when 8% CCN-COS-AgNP(mass ratio) introduced. When 10%(mass added, nanofibers showed an excellent activity S. aureus(Staphylococcus aureus) E. coli(Escherichia coli), maximum inhibition zones 2.30 1.60 cm, respectively. Moreover, 2%(mass fibrous membrane 126% cell viability mg63 human osteoblasts. electrospun has great potential application in biomedical field.
