Advanced dielectric materials are largely demanded in many engineering applications such as power electronics, dielectric capacitors, electronic packaging, and electromagnetic shielding. Ferroelectric ceramics (FCs) are high-dielectric constant materials with relatively lower breakdown strength than polymeric dielectric materials. While polymer materials (PMs) have large breakdown strength but suffer low dielectric constant. Various efforts have been made in developing a single material with simultaneous high dielectric constant and breakdown strength by combining the PM (as a matrix) and the FC (as reinforcement). In many cases, high agglomeration and incompatibility of such material combination are hurdles facing this class of composite materials. However, various studies have tried to address the challenges via interface tailoring. Basically, it involves surface modification or functionalization of FCs to meet appreciable compatibility with PMs, which have shown positive results in this regard. Therefore, this chapter focused on the synthesis, characterization, and contribution of surface functionalization on dielectric properties of FC-PM composites. This chapter gives insight on advancement of dielectric responses of functionalized FC-based composites, current challenges, recommendations, and applications.
