Fabrication of Lead Titanate Pb Ti O3 Nanofiber Mats Via Electrospinning.

We report an electrospinning approach to producing Pb Ti O3 polycrystalline nanofibers. The influence of the polymer concentration in the solution on the obtainable Pb Ti O3 nanofiber morphology was investigated. Nanofibers were characterized by high-resolution scanning electron microscopy ( HR- SEM) and Raman spectroscopy. After annealing at 500°C for 3 h, the continuous structure of nanofibers remained intact. Only tetragonal Pb Ti O3 was identified by Raman spectroscopy. Piezoelectric behavior of Pb Ti O3 nanofiber mats was demonstrated by making a nanomat-based voltage generator with peak output voltage >1 V. [ABSTRACT FROM AUTHOR]
