Dielectric materials with high permittivity and low dielectric loss are preferred for increasing insulation. Compared with metals or ceramics, polymer composites have proven to be good alternatives due to their exemplary material properties such as flexibility, machinability and adjustable dielectric properties. Besides, it is important to develop a novel material that has greater dielectric properties and one that uses sustainable materials in order to satisfy the growing field of green engineering. In this research paper, the dielectric constants, and dielectric losses are investigated to find the right composition of PLA-PHA blended, surface treated flax fiber infused biopolymer composites. Also, the factors that affect these properties such as interfacial polarization, dipole polarization have been explained according to the results obtained. The results obtained showed an increased dielectric constants and decreased dielectric loss at certain frequencies due to the inclusion of conductive copper fillers, surface treated flax fibers and a biopolymer mixture.
