Abstract
A composite of epoxy embedded with a giant dielectric constant material CaCu3Ti4O12 (CCTO) was fabricated. Various theoretical models were employed to rationalize the dielectric behavior of these biphasic composites. Amongst different models that were employed to predict the dielectric properties of the composites, the effective dielectric constants (εeff), obtained via Yamada model were in close agreement with the experimental values. A metallic inclusion in CCTO/epoxy composite was found to be effective way to enhance its dielectric constant. A three phase percolative composite (Al-CCTO/epoxy) was fabricated and percolation theory was employed to describe its dielectric behavior.
