Abstract: | Polyethylene oxide (PEO) has been introduced into HNbWO6·1.5H2O using melt-intercalation technique and its effect on the structure and properties of the host material studied using powder X-ray diffraction, FT-IR, impedance spectroscopy and TGA/DTA measurements. The intercalation reaction leads to loss of stacking coherence along the c-axis of the host layered material, as evidenced by the XRD data. FT-IR spectra of the nanocomposite show changes, indicative of complexing of the guest polymer with the host layered structure. TGA/DTA isothermal profiles exhibit marked changes upon prolonged periods of intercalation. The conductivity of the nanocomposite is found to be about 2×10−6 S/cm. |
