Fabrication of Highly Photoluminescent TiO₂/PPV Hybrid Nanoparticle‐Polymer Fibers by Electrospinning

In this study, we have synthesized highly photoluminescent TiO 2 /poly (phenylene vinylene) (PPV) hybrid nanoparticle‐polymer fibers by electrospinning a PPV precursor added to a TiO 2 sol‐gel solution. The diameters of the hybrid fibers ranged from 100–300 nm and the average size of TiO 2 nanoparticles within the fibers was 10–60 nm. FT‐IR analysis indicated that a new band around 1 632 cm −1 assigned to the TiOC vibration appeared, which resulted in the stronger luminance of the fluorescence of the TiO 2 /PPV hybrid fibers compared to free standing PPV nanofibers. magnified image
