| Abstract | ||
| The dielectric and a.c. conductivity behavior of CB / PVC (cement) composites was studied. The measurements were taken in the frequency range from 1kHz to 1MHz and the temperature range from 30 oC to 90 oC. The composites permittivity ε' shows a strong dependence on CB loading and increases as CB loading increases until percolation at (~ 13% vol) loading is reached after which decreases sharply to zero . Frequency dependency of ε' show dependence on filler loading, at low CB loading percentages , έ is nearly stable versus frequency . ε' increases with the temperature rise of the composites. The a.c conductivity increases with the increase of loading and temperature, and shows frequency independency at higher loading. | ||
