The dielectric studies of semi-crystalline Nylon 11 filled with a conducting polymer (PANI) were investigated in a wide range of frequency and temperature by using Impedance Analyzer. The main focus was on the effects of conducting filler content on dielectric properties of Nylon 11. The prominent factors such as dielectric permittivity, loss factor, and loss tangent were studied at high frequency. Two different concentrations (1 % and 5 % w/w) of the conducting filler were used. It was observed that with the increase of fillers concentration, the value of dielectric permittivity (ε’)б The dissipation factor (ε’’) and loss (tan ) decrease compared to pure Nylon 11.
