The dielectric and electrical proprieties of Ethylcarbazole family based copolymer such as Poly(Ethylcarbazole-Terphenyl) (PEcbz-Ter), Poly(Ethylcarbazole-Anthracene) (PEcbz-Ant) and Poly(Ethylcarbazole-Furan) (PEcbz-Fur) were investigated over the frequency range from 1 kHz to 2 MHz. The dielectric constant ε'r for (PEcbz-Ter), (PEcbz-Ant) and (PEcbz-Fur) pellets was found to decrease as the frequency increases and it was recorded a value of 11 7 , 11 6 and 7 6 respectively at 1 kHz. The dielectric loss was investigated and have a value below 1% at 11 kHz, which is suitable for several energy storage applications.
