In recent years there has been an increasing need in obtaining high-permittivity (high-k) materials due to rapid development of electrical/electronic industry. In practice, these materials are mainly designed and employed as polymeric composites containing different ceramics, conductive metallic and non-metallic fillers. Each kind of these fillers may improve the dielectric properties of the final composite by a specific mechanism. Use of ceramics is a more common approach and those of conducting fillers and a combination of ceramics and conducting particles are of later methods. This is a brief report on basic definitions, methods of increasing the dielectric constant, recent advances and research efforts toward achieving high dielectric properties, including high-k and low dielectric loss tangent for polymer composite.
