A review of high-entropy materials with their unique applications.

High-entropy materials (HEMs) constitute an innovative category of advanced materials distinguished by their distinctive atomic arrangements and remarkable multifunctional attributes. This thorough overview critically analyzes the core principles, synthesis methods, and novel applications of HEMs, emphasizing their transformative potentials in electromagnetic and biological fields. This study examines how the high configurational entropy effect, lattice distortion, and slow diffusion mechanisms facilitate the stabilization of single-phase systems including numerous primary elements.
