“…However, the large filling ratio, narrow absorption bandwidth, and poor machinability limit their application scenarios. With the rise of wearable and foldable devices, there is an increasing demand for flexible EMW-absorbing materials. − At present, plenty of flexible EMW-absorbing materials have been developed, such as foams, − aerogels, − films, − hydrogels, − and so on. , The abundant pore structure inside foams and aerogels can not only reduce the weight of the materials but also provide space for EMW to reflect and scatter, which is conducive to enhancing the absorption capacity of materials. However, the limited flexibility and stretchability hinder their further development.…”
