Electrical and morphological characterization of a nickel-polyester composite prepared by spreading and spraying techniques

Nickel-Polyester samples were produced using polyester resin and metallic particles of nickel. A scanning electron microscopy study shows that the prepared surface produced from nickel particles dispersed in the polyester and thermally treated consists of a porous network. Nickel-Polyester composites with resistivity values around 10(-1)-10(-3) Ohm cm have been analysed as potential oxygen evolution electrodes in an alkaline medium. The dependence of the electronic parameters on the morphological features of the nickel-polyester samples is evident from the study carried out with samples prepared at different conditions.
