|Abstract:||Different concentrations of organometallic compound (ferric oxalate) have been dispersed in polyvinyl chloride (PVC) films. PVC has been synthesized by solution polymerization technique. These films have been irradiated with 3 MeV protons at a fluence of 110¹³ ions/cm². The frequency response of dielectric behaviour has been studied both in pristine and irradiated samples using LCR meter in the frequency range100 Hz-10MHz. The results so obtained are explained using the universal law of dielectric behaviour (ε α f ⁿ⁻¹). The results are also explained on the basis of intra-cluster motion. It is observed that the log conductivity increases with increase in metal concentration and also with the fluence. The dielectric constant/loss shows frequency dependent behaviour. SEM studies show that the particle size of metal compound decreases upon irradiation.|
