摘要：

应用静电纺丝法并结合Sol-gel 技术制备了SrTiO3微纳米纤维. SEM, TEM及电子衍射分析结果显示, 于900 ℃煅烧获得的纤维直径分布在50~400 nm之间, 其典型直径约为280 nm. XRD分析结果表明, 纤维由立方结构的SrTiO3晶粒组成, 平均晶粒尺寸为33 nm.

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
