Abstract:
Hybridization of polymeric porous membranes based on electrospun nanofibers with photocatalytic materials is of great importance in medicine and environmental applications. Here, a flexible and wettable electrospun polyacrylonitrile (PAN) nanofibers were prepared as freestanding substrate to grow zinc oxide nanorods (ZnO NRs) on them. The morphology and crystal structure of synthesized hybrid membrane of ZnO NRs/PAN nanofibers were characterized by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD), respectively. The average diameters of PAN nanofibers and ZnO nanorods grown on PAN mat were 211 and 170 nm, respectively. Also, the average length of ZnO was about 1.2 μm. The XRD pattern showed the hexagonal wurtzite crystal structure of ZnO. In addition, the membrane surface hydrophilicity was investigated by water contact angle (WCA) measurements. The photocatalytic disinfection against Staphylococcus aureus bacteria showed that the nanofibrous membrane have a good removal efficiency from aquatic solutions.
