Abstract: | This article reports the development, DC conductivity behavior of carbon soot filled polyester graded composites. Carbon soot filled polyester composites having 3 wt% of carbon soot powder and polyester resin were prepared. DC conductivity measurements were conducted on the graded composites by using an electrometer in the temperature range of 28°C to 150°C. DC conductivity increased with increase in carbon soot concentration in the composites; DC conductivity increased with the increase in temperature. Activation energy was calculated by using Arrhenius equation for graded samples exhibited electronic conduction. Linear dependence of pre-exponential factors on activation energy for carbon soot filled polyester graded composites reveals semi-conducting behavior of the composites. |
