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

Figure 9

Relaxation processes of the EPDM specimen at seven temperatures ranging from 233 K to 404 K. Four relaxation processes, α (red dashed line), β (blue dashed line), MWS (orange dashed line), and conductivity (navy dashed line), contribute to the imaginary permittivity data. (a) 404 K (b) 374 K (c) 344 K (d) 313 K (e) 281 K (f) 257 K, and (g) 233 K.
