A comprehensive review on dielectric composites: Classification of dielectric composites

In this review paper, the complete discoveries of dielectric materials from ceramics to polymer composites and concepts that lead to applying these materials in actual applications are reviewed. The basic principles of dielectric behavior in composites systems have been enumerated in this review. The reader can also understand how models of polarizations are intertwined with composite fabrication to yield the desired dielectric properties, and the combinations of different components in a composite for addressing engineering solutions are thoroughly studied in this review. Furthermore, the recent discoveries of dielectric composite materials have been classified, and their material properties have been reviewed as well. Notable reviews for composites in this article are mainly ceramic-based dielectric composites, polymer-ceramic dielectric composites, natural fiber reinforced polymer composites (NFRPCs), and bio-based polymer dielectric composites. Lastly, the processing techniques of all the mentioned dielectric materials have been comprehensively reviewed, and their prominent applications have been discussed as well.
