Recent Progress of One-Dimensional Nanomaterials for Microwave Absorption: A Review

Abstract

With the increasing problems of electromagnetic interference and electromagnetic radiation, electromagnetic wave absorption (EMWA) materials have received considerable attention in civil and military fields. Among various EMWA materials, one-dimensional (1D) nanomaterials are recognized as a very promising candidate because of their unique aspect ratio, special shape anisotropy, large specific surface area, and simple manufacturing process. Herein, this paper presents a comprehensive review of recent research progress of 1D nanomaterials for EMWA applications, with a special focus on the advances in general preparation strategies and microscopic structure construction. Furthermore, the current challenge and future prospect of 1D electromagnetic absorbers are proposed, which should provide some guidelines for the design of advanced EMWA materials.

High-Performance Microwave Absorption Materials: Theory, Fabrication, and Functionalization

“…Therefore, the combination of dielectric loss and magnetic loss is highly urgent. The combination of dielectric loss and magnetic loss can not only improve the impedance matching, but also enhance the microwaves attenuation . Herein, we introduce some electromagnetic synergistic loss MAMs, mainly including carbon-based magnetic MAMs combining carbon and magnetic materials, and MXene-based composite MAMs based on MXene and other materials.…”
