【摘要】SrMnO3/polyvinylpyrrolidone (PVP) composite nanofibers have been prepared successfully by electrospinning from strontium (Ⅱ) nitrate and manganese(Ⅱ) acetate tetrahydrate. The hexagonal SrMnO3 nanofibers was obtained after calcination at 800 ℃ for 3 h. The effect of PVP concentration was investigated. The structure and properties of nanofibers were characterized. The results showed that SrMnO3/PVP composite nanofibers became uniform and the beaded structure disappeared when the mass fraction of PVP reached 8%; PVP completely decomposed and all the feedstocks transformed into SrMnO3 during the calcination at 700 ℃, thus a goodpurity hexagonal SrMnO3 fibers of 150-200 nm in the diameter were obtained.
