Electrospun polycaprolactone/zno nanocomposite membranes with high antipathogen activity

HIGHLIGHTS

SUMMARY

    The authors synthesized polycaprolactone nanofibers (PCL-ref), then deposited a thin polymeric carboxy-containing layer from a CO2 /C2 H4 /Ar gas mixture onto the surface of plasma-modified nanofibers (PCL-COOH), and finally deposited positively charged ZnO NPs (zeta potential +54 mV) on the surface of negatively charged PCL-COOH to ultimately produce PCL ZnO composite. The PCL-ZnO filter demonstrated 100% antimicrobial (Escherichia coli U20, Staphylococcus aureus CSA154)/antifungal against (Neurospora crassa/anti yeast (Candida parapsilosis ATCC90018) activity due to incredibly high concentration of ZnO NPs (≥5 at.%). To immobilize ZnO NPs . . .
