In this work, we report the fabrication and deodorizing efficiency of nanostructured core‐sheath TiO 2 nanofibers prepared by a combined technique of electrospinning and metallization. The morphologies and crystal structures of the resultant nanofibers were investigated by emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), and wide angle X‐ray diffraction (WAXD), respectively. The influence of annealing conditions, such as annealing temperature and time, various titanium isopropoxide (TTIP) weight fractions, which are based on the weight of the poly(vinyl acetate) (PVAc), on morphologies and crystal structures was evaluated for the nanostructured core‐sheath TiO 2 nanofibers. UV blocking properties and deodorizing efficiency were also measured by UV‐visible spectrometer and formaldehyde detector tube at room temperature, respectively. © 2012 Wiley Periodicals, Inc.
