In this study, poly(vinyl pyr - rolidone) (PVP) dissolved at 4 wt% concentration in dichloromethane (DCM) con- taining titanium oxide (T iO ) nanoparticles was used as polymer feed solution for electrospinning under pressurized carbon dioxide (C O ) at temperature of 30  °C, pressure of 5 MPa, and applied voltage of 10–14 kV. Scanning electron microscopy (SEM) revealed that the PVP fibers electrospun with and without TiO nanoparticles exhibited the same morphology with hollow structure and average pore diameter of 2–7 μm. Fourier-transform infrared (FT-IR) spectroscopy revealed that the electro- spun PVP fibers had properties similar to the PVP starting material. X-ray photo - electron spectroscopy (XPS) revealed that the TiO nanoparticles were present in the residue after thermogravimetric (TG) analysis of electrospun fibers.
