Research status and future perspectives of low dimensional electromagnetic wave absorption materials

Abstract

In this study, we briefly review the different EMW absorption mechanisms and key influencing factors, then present the latest developments in low-dimensional (LD) EMW absorption materials.

Graphene/silver nanowire aerogel sponge for highly effective electromagnetic energy attenuation

“…2,3 As a reliable technology to alleviate electromagnetic pollution, microwave absorption (MA) materials have generated intense interest among researchers. Low-dimensional materials, such as one-dimensional (1D) carbon nanotubes (CNTs), 4 metal nanowires, 5,6 carbon nanofibers, 7 two-dimensional (2D) graphene, 8 transition metal carbide/nitride (MXene), 9,10 and metal sulfide, 11 are employed as highly effective microwave absorbers due to their excellent conductivity, light weight, high aspect ratio, and large specific surface area. 8 Therefore, intense efforts have been committed to the design and preparation of low-dimensional microwave absorbers.…”

“…In particular, strong conduction loss dependent on morphology anisotropy is extremely easy to attain using the above materials. 8,9,13…”
