Recent advances in perovskite-derived microwave absorption materials

The growing concern over electromagnetic pollution necessitates the development of high-performance microwave absorption materials. Perovskites have emerged as promising candidates due to their unique crystal structure and tunable electromagnetic properties. This comprehensive review systematically elucidates the crystallographic characteristics, functional properties, and structural classifications of perovskite materials, and summarizes recent advances in perovskite-based microwave absorbers over the past decade. Critical analyses include synthesis methodologies, performance optimization strategies with a focus on defect engineering, hetero-structure design, multi-component hybridization, and microwave absorption enhancement. Current challenges are critically assessed, including limited high-frequency absorption (8-18 GHz) and scalability issues associated with complex perovskite structures. Finally, perspectives are discussed for the design of next-generation perovskite-derived microwave absorption materials.
