Abstract: | Dielectric measurements of pure Nylon 11 in comparison with metal (Zn) filled Nylon 11 have been carried out using an impendence
analyzer in the frequency range of 102–107 Hz and temperature range 20–120 °C. Two different concentrations (1% and 5% (w/w)) of metal (Zn) fillers were used. It was
observed that at low frequencies and particularly at high temperature dielectric permittivity (ε′) for 1% Zn filled sample
is more than that of pure Nylon 11 whereas ε′ for 5% Zn filler is less as compared to that for pure Nylon 11. But at very
high frequencies dielectric permittivity (ε′) for pure Nylon 11 is less than Zn filled samples. Also it is found that for
all frequencies and particularly at high temperature ε′′ as well as tan δ are maximum for pure Nylon 11 and decrease for filled Nylon 11 samples. The Cole–Cole arcs have also been plotted for these
samples. Using these plots the static and instantaneous values of dielectric permittivity and orientation polarization parameter
‘S’ have been calculated. |
