Surface Characterization of Electrically Conducting Nickel Tetrathiooxalate/Poly(vinyl alcohol) Composites
Abstract
Nickel (II) acetate, complexed in poly(vinyl alcohol) (Ni/PVA) has been reacted with tetraethylammonium tetrathiooxalate (TEATTO) to form a semiconductive composite (NiTTO/PVA). The resulting materials are air stable and mechanically durable with conductivities up to .001/ohm cm. Examination of the surfaces by X-ray photoelectron spectroscopy (XPS) prior to treatment with TEATTO indicates the Ni/PVA surface to contain Ni(II) in an octahedral coordination. After reaction with TEATTO to form NITTO/PVA the Ni(II) is observed to be in a square planar coordination. The chemistry and composition of the Ni/PVA precursors, their TEATTO reaction products and model compounds, as characterized by XPS and static secondary ion mass spectrometry (SSIMS), are compared and contrasted.
