A review on structure–property relationships in dielectric ceramics using high‐entropy compositional strategies

Abstract High‐entropy strategy is a design that uses multiple elements to increase configurational entropy. As an emerging research field, high‐entropy was originally applied to metals, but it has shown great potential in inorganic nonmetallic materials. Since the first discovery of colossal dielectric permittivity in high‐entropy ceramics, it indicates that the high‐entropy strategy is feasible in dielectric ceramics. The multi‐ion solid solution will bring a broader space for the material structure and property tailoring. With the research of domestic and foreign scholars in high‐entropy dielectrics, we believe that entropic engineering can effectively regulate dielectric properties. The review paper explores the potential of the high‐entropy strategy in dielectric ceramics. It provides a detailed overview of the structural properties and the potential benefits of utilizing high‐entropy materials in dielectric ceramics. The review also covers the current research advancements in the field and provides insights into future directions for further development of high‐performance dielectric ceramics.
