Authors have developed films of pure Poly-methyl-methacrylate (PMMA) and(0.5%, 1%, 2% and 5%) Potassium permanganate (KMnO4) doped PMMA composite films of thickness (~100m) using the solution cast technique using dichloromethane as a solvent. Dielectric behavior of these composite films have been investigated using an impedance analyzer at room temperature and frequencies in the range 100 Hz to 100 KHz. Results show that the dielectric parameters like dielectric constant (’), dielectric loss (''), loss tangent (tan) and a.c. conductivity () of these composite films change with frequency and change in concentration of KMnO4. The dielectric constant and dielectric loss decrease with increase in frequency whereas decreases with increase in concentration of potassium permanganate. From the results we can conclude that KMnO4/PMMA nano composite films can be used as a potential dielectric for charge separation as well as for timing, filtering etc.
