“…Despite the many advantages of MMAs, this type of microwave absorber has a narrow absorption bandwidth, which is mainly related to the strong magnetic and electric resonances (Sood and Tripathi, 2015;Cheng et al, 2017a;Xin et al, 2017). To solve this issue, researchers have designed dual, multi, and broadband MMAs with high absorbing performance (Hu et al, 2016;Lian et al, 2016;Rufangura and Sabah, 2016;Wang, 2016). Some researchers have proposed enhancing the bandwidth by employing multi-resonance units with diverse geometric dimensions (Li et al, 2011;Ghosh et al, 2013;Park et al, 2013;Viet et al, 2014).…”

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.
