Ag-Poly E-caprolactone Nanofibers

Antimicrobial nanoflbers of poly(e-caprolactone) (PCL) were prepared by electrospinning of a PCL solution with small amounts of Ag-loaded zirconium phosphate (AgZ) nanoparticles for potential use in biomedical applications [41]. SEM, EDX, and XRD investigations of the electrospun flbers confirmed that Ag-containing nanoparticles were incorporated and well-dispersed in smooth PCL nanoflbers [41]. In another study, PCL-based polyurethane (PCL-PU) nanoflbers containing Ag nanoparticles for use in antimicrobial nanofllter applications were prepared by 

Recently, PCL containing bovine bone hydroxyapatite (HA) and hydroxyapa-tite/Ag (HA-Ag) composite nanoflbers were prepared via an electrospinning process [43]. The morphology, structure and thermal properties of the PCL, PCL/HA, and PCL/HA-Ag composite nanoflbers before and after immersion in SBF were characterized. SEM images revealed that the nanoflbers were well-oriented and incorporated the HA-Ag nanoparticles well. Mechanical study revealed that the yield stress of PCL/HA-Ag composite nanoflbers showed a higher value than that of PCL/HA composite, possibly due to the addition of metallic Ag nanoparticles [43].
