| چکیده | ||
| The thermally stimulated discharge (TSDC) current is studied for acrylonitrile butadiene rubber (NBR) loaded with different high abrasion furnace carbon black (HAF). TSDC peak appears only for higher HAF contents > 60phr (70 and 80phr of HAF contents), the TSDC spectra consist of a sharp peak corresponding to a peak temperature Tm which is slightly shifted to higher temperature for 70phr loaded NBR samples and to lower temperature for 80phr loaded NBR sample, with poling field (10V/cm to 50V/cm). The activation energy U and relaxation time for TSDC peak were calculated using the initial rise method. The calculated values of U are nearly constant for sample 70phr and slightly increase for sample 80phr with increasing poling field Ep . The calculated values of at peak temperature Tm are nearly constant for two samples (70phr & 80phr) with different poling field, whereas the calculated values of relaxation time at To = 300K increased with increase of poling field. | ||
