Preparation of Nanoporous Fibers of BaTiO₃ via Electrospinning of BaTiO₃/PVC and Thermal Treatment Effects

Abstract

Preparations of barium titanate microfibers made by electrospinning using a suspension of BaTiO3/PVC resin solution are described in this paper. The electrospun fibrous membrane of ceramic/PVC composite was heat treated at 600°C, 800°C and 1000 °C for 1 hr in air to remove organic components. The morphology and compositions at room temperature and the caused by effect of calcination on the fibrous membrane BaTiO₃/PVC composite were investigated by SEM and ZAF. Typical fiber diameter was obtained between 14 μm and 20 μm with fibers lengths exceeding 500 μm with nanoporous whose diameters were formed between 350 nm and 700 nm into the microfibers.
