The electrical properties of wollastonite inlaid NR/SBR type elastomer based material have been evaluated. Electrical properties
of the samples were measured in the temperature range of 303 to 453 K and the frequency range of 100 Hz – 40 MHz.
All electrically measured parameters were given anomalies at 385 K. Only one type of dielectric relaxation process have been
observed for all measurements. Physical parameters characterizing the dielectric behavior have been obtained by fitting
the experimental results in the modified Debye equation. The activation energy which is thermally activated by dielectric
relaxation process have been calculated to be 0.58 eV. DC conductivity increasing by temperature has been explained with
the help of VFT model whereas the AC one has been clarified by the OLPT model. |
