Abstract
PurposeThe purpose of this paper is to study the preparation and characterisation of poly(p‐phenylene vinylene), PPV/TiO2 photoluminescent (PL) nanofibres, and the causes of the blue‐shift in PL spectrum of the as‐prepared composite nanofibres.Design/methodology/approachA simple method coupling sol‐gel method and electrospinning technology was used to prepare PPV/TiO2 nanofibres from precursory PPV solution.FindingsSmall‐angle X‐ray diffractometer showed that the nano‐TiO2 was mainly amorphous in composite nanofibres. The PL spectrum of the composite nanofibres confirmed the conclusion that there was a slight blue‐shift in the PL spectrum owing to the existence of TiO2 nanoparticles.Research limitations/implicationsThe nanofibres collected aligned in random orientation, if parallel nanofibres were obtained. Practical applications will be effected.Practical implicationsThe electrospinning method provides an effective strategy for preparing polymer composite nanomaterials.Originality/valueComposite nanofibres will have potential applications for green optical/electric devices such as LEDs, sensors, transducers and flat panel displays.
