Characterization of Dielectric Relaxation Process by Impedance Spectroscopy for Polymers: Nitrile Butadiene Rubber and Ethylene Propylene Diene Monomer

Figure 3

An example of the decomposition of two relaxation processes in NBR by the dispersion analysis program at 275 K. (a) Real (red line) and imaginary (blue line) fitted permittivity values versus the frequency for all temperatures and (b) the decomposition of the two relaxation processes by the dispersion analysis program. In (b), the measured real (red ×) and imaginary (blue ×) permittivity and the fitted real (red line) and imaginary (blue line) permittivity graphs at 275 K are shown, and their fitted parameters are listed at the bottom table.
