Abstract
SrMnO 3 /Polyvinylpyrrolidone (PVP) composite nanofibers have been prepared successfully by electrospinning from Cerous(II) nitrate and Manganese(II) acetate tetrahydrate, after the heat treatment at 800 °C for 3 h, the hexagonal SrMnO 3 nanofibers was obtained. The effect of PVP concentration was investigated. The size and morphology, phase information, thermal properties of nanofibers were characterized by SEM, EDX, XRD, TGA, FT-IR, respectively.
Highlights
Electrospinning technique is extensively employed to synthesize some ultrafine, continuous and uniform diameter nanofibers of polymers, composites and ceramics for its advantages such as briefness, versatility, time saving and low cost [1, 2]
The size and morphology of SrMnO3 fibers were observed with JEOL JSM-6390 scanning electron microscope (SEM)
Energy dispersive X-ray (EDX) spectrograph was recorded for the elemental analysis to investigate the phase purity of SrMnO3 nanofibers using INCA 200 EDS, attached with SEM
Summary
Electrospinning technique is extensively employed to synthesize some ultrafine, continuous and uniform diameter nanofibers of polymers, composites and ceramics for its advantages such as briefness, versatility, time saving and low cost [1, 2]. SrMnO3 powders have been synthesized with many methods such as high temperature solid-state reaction, coprecipitation [16], sol-gel, etc [17,18,19,20]. Nanofibers can be prepared via electrospinning combined with sol-gel process. * Corresponding author: zhuhua2006@163.com synthesized by electrospinning, the inorganic-polymeric fibers would transform into nanofibers by subsequent calcinations at high temperature.
