"Polyvinyl chloride (PVC) was chosen to be loaded with various amounts of high abrasion furnace black (HAF). The mechanical as well as electrical properties of the prepared composites were investigated," scientists in Cairo, Egypt report.
"The dielectric properties of these composites were investigated in the frequency range 10(2)-10(5) Hz at a temperature range of 30-120 degrees C. In addition to the conductivity term, the experimental data of the dielectric losses epsilon '' were analyzed using a computer program based on both Havriliak-Nagami and Frohlich equations into two relaxation processes. The first relaxation process in the lower frequency range could ...
