Abstract

A wet chemical synthesis method is reported for the preparation of polymer stabilized ultrafine palladium iodide particles within the size range of 5-8 nm. The X-ray photoelectron spectroscopy analysis confirmed the formation of palladium iodide with Pd(i)-like species. The dipolar response of the synthesized organic-inorganic hybrid system has been investigated under different temperature and frequency conditions. The dielectric constant value exhibited an inverse relationship with the temperature and the maximum value of ∼595 was achieved at 100 Hz. The maximum polarization and the remnant polarization values of the palladium iodide nanoparticle based sample were 0.20 μC cm−2 and 0.145 μC cm−2, respectively, under 2 kV mm−1 field conditions at 100 Hz. We also have explored the dielectric and electric field driven polarization performance of the palladium iodide nanoparticles under in situ synthesis conditions.
