Abstract

Abstract:

Perorskite strueture SrTiO₃ ultrafine fibers were successfully fabricated via electrospinning combined with Sol-gel technology. Polycrystalline SrTiO₃ fibers with a diameter range of 50—400 nm were obtained with calcination of the inorganic/organic hybrid fibers at 900 ℃ for 1 h. The morphology, microstructure, crystal structure and thermal analysis were investigated via SEM, TEM, XRD and TG-DSC, respectively. The results show that the crystalline phase and morphology of SrTiO₃ fibers were greatly influenced by the calcination temperature.

Key words: Electrospinning, Sol-gel, SrTiO₃, Ultrafine fibers
