Nickel II acetate, complexed in polyvinyl alcohol NiPVA has been reacted with tetraethylammonium tetrathiooxalate TEATTO to form a semiconductive composite NiTTOPVA. The resulting materials are air stable and mechanically durable with conductivities up to .001ohm cm. Examination of the surfaces by X-ray photoelectron spectroscopy XPS prior to treatment with TEATTO indicates the NiPVA surface to contain NiII in an octahedral coordination. After reaction with TEATTO to form NITTOPVA the NiII is observed to be in a square planar coordination. The chemistry and composition of the NiPVA precursors, their TEATTO reaction products and model compounds, as characterized by XPS and static secondary ion mass spectrometry SSIMS, are compared and contrasted.
