Abstract
The development of novel material configurations for achieving high-performance electromagnetic interference (EMI) shielding remains challenging. To effectively address this issue, in this work, a structure composed of Ag-modified whisker carbon nanotube (Ag@WCNT) coated with 2D MXene composite is fabricated. The proposed EMI shielding material with different structures (double-layer and sandwich structures) exhibited high shielding effectiveness close to 85 dB at X-band. Its lightweight structure allowed for efficient shielding without significant weight gain, which is especially important in applications such as aerospace, mobile communications equipment, and others where lightweight is required. The high degree of tunability of these composites can be leveraged for meeting specific application requirements. This property renders them promising candidates for a wide range of electromagnetic shielding applications.
开发新型材料配置以实现高性能电磁干扰（EMI）屏蔽仍然具有挑战性。为有效解决这一问题，本研究制作了一种由二维 MXene 复合材料涂覆的 Ag 改性晶须碳纳米管（Ag@WCNT）组成的结构。所提出的 EMI 屏蔽材料具有不同的结构（双层结构和三明治结构），在 X 波段具有接近 85 dB 的高屏蔽效能。其轻质结构可在不显著增加重量的情况下实现高效屏蔽，这在航空航天、移动通信设备等要求轻质的应用中尤为重要。这些复合材料的高度可调性可用于满足特定的应用要求。这一特性使它们成为各种电磁屏蔽应用的理想候选材料。
