Through photocopolymerisation of the cluster Zr₄O₂(OMc)₁₂ bearing 12 polymerisable groups with methylmethacrylate in a monomer:cluster molar ratio of 50, a novel inorganic-organic hybrid thin film was obtained. The prepared thin film, having a thickness of about 70 m, was characterised through dielectric spectroscopy. The dielectric spectra of the film were measured at different temperatures (20-73.4 °C) and in the frequency range 20 Hz-1 MHz. The and relaxations typical of polyalkylmethacrylate polymers were detected and the electric response mechanisms were investigated by analysing the dielectric spectra in terms of the Davidson-Cole phenomenological equation. Finally, a dielectric constant of 1.93 at 25 °C and 1 kHz was determined. This value classifies this system as a promising dielectric material for the development of electronic devices, such as polymer based field effect transistors.
