(a) TEM of core-shell fibers prepared by coaxial electrospinning. 10 wt% aqueous polyvinyl alcohol (PVA) was employed as the core, whereas 8 wt% polyvinylpyrrolidone (PVP) dissolved in dimethylformamide (DMF) as the shell. The electrospinning was performed at the applied electric field strength of 1.5 kV/cm, (b) SEM image of the hollow TiO₂ nanofibers.
