Preparation and characterization of NiO nanofibres via an electrospinning technique

Thin PVA/nickel acetate composite fibres were prepared by using sol–gel processing and electrospinning technique. After calcinations of the above precursor fibres, NiO nanofibres with a diameter of 50–150 nm could be successfully obtained. The fibres were characterized by SEM, FT-IR, WAXD, respectively. The results showed that the crystalline phase and morphology of NiO fibres were largely influenced by the calcination temperature.
