“…Microwave-absorbing materials play a crucial role in preserving human and environmental health by controlling and reducing electromagnetic pollution (Peymanfar et al, 2021a;Lv et al, 2021;Cheng et al, 2022;Lei et al, 2022;Lou et al, 2022). The vital factors mitigating microwaves are magnetic and dielectric losses by converting electromagnetic energy to heat energy (Peymanfar and Fazlalizadeh, 2021;Yang et al, 2022a).…”

Microwave-absorbing materials are widely utilized in military and civilian applications. Moreover, their environmental potential to refine electromagnetic pollution has promoted their importance. An ideal conjugated organic polymer for use as a microwave-absorbing material should possess high porosity, low density, a long conjugated backbone, a narrow energy band gap, proper conductive and relaxation loss, and vast specific surface area. This review describes the conductive polymer types used as microwave-absorbing material and their composites toward improving microwave-absorbing capability. Additionally, recent developments in synthetic strategies and structural properties of pure carbon-based microwave-absorbing materials and other conjugated structures having heteroatoms in their chains are discussed. In the field of microwave absorbers, the predominant microwave-absorbing mechanisms among conductive polymers and their composites as well as the special mechanisms for tuning microwave-absorbing characteristics, including metamaterial and quasi-antenna features, are dissected. This review sheds new light on architecting low-density and high-performance microwave-absorbing structures and offers new prospects in tailoring conjugated polymers based on their dominant mechanisms.
