Description In this work, electrospinning method was used for preparation of ceramic nanofibres from PVA/Al(NO3)3·9H2O precursor solution. Six solutions with different concentration of PVA/Al(NO3)3·9H2O were prepared and nanofibres from each solution were spun. Precursor nanofibres were treated in DCSBD plasma (diffuse coplanar surface barrier discharge) for 10 minutes. Later were fibres thermally treated in furnance till 100/250/1000 °C. Calcinated nanofibres were studied by FTIR analysis, scanning electron microscopy and thermogravimetry.
