Novel methods to fabricate PbS/poly(p‐phenylene vinylene) composite fibres
Abstract
Purpose
The purpose of this paper is to investigate three preparation processes and the photoluminescent (PL) properties of PbS/poly(p‐phenylene vinylene) (PPV) composite fibres.
Design/methodology/approach
By the combination of electrospinning technology, chemical vapour deposition and chemical liquid deposition, PbS/PPV composite nanofibres were prepared by three simple methods. The morphologies of the fibres and the PL properties were researched with the transmission electron microscopy (TEM) and the eclipse fluorescence spectrophotometer.
Findings
By different synthetic methods, the dispersion morphologies of PbS nanoparticles and the PL properties of their respective PbS/PPV composite fibres were different. Moreover, the effects of PbS nanoparticles on the luminescence quenching of the PPV were observed in all the synthesised PbS/PPV composite fibres, respectively.
Research limitations/implications
The dispersion morphologies of PbS nanoparticles were not uniform enough.
Practical implications
A new method was used for preparing nanoparticles/polymer composite fibres.
Originality/value
The combination of electrospinning technology and chemical liquid deposition was used for the first time to fabricate the sulfide/polymer composite fibres. In addition, we hope that the results obtained here will provide some useful evidences for the interaction mechanism between IV‐VI group semiconductors and conjugated polymers, and the prepared composite fibres will have applications in the nano‐optoelectronic field.
