Preparation and characterisation of poly(p‐phenylene vinylene)/semiconductor nanofibres

Abstract

Purpose

The 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/approach

A simple method coupling sol‐gel method and electrospinning technology was used to prepare PPV/TiO₂ nanofibres from precursory PPV solution.

Findings

Small‐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/implications

The nanofibres collected aligned in random orientation, if parallel nanofibres were obtained. Practical applications will be effected.

Practical implications

The electrospinning method provides an effective strategy for preparing polymer composite nanomaterials.

Originality/value

Composite nanofibres will have potential applications for green optical/electric devices such as LEDs, sensors, transducers and flat panel displays.
