摘要

传统金属和铁氧体吸波材料在重量、厚度和吸收强度上存在局限，难以满足现代电子设备的微波防护需求。二维片状Hofmann型金属有机框架材料（MOFs）因结构有序、界面清晰及制备简便，为高效吸波材料提供了新途径。以Co[Ni(CN)₄] MOF为前驱体，通过可控碳化构建二维CoNi/C复合材料，实现NiCo纳米颗粒均匀嵌入连续碳相，形成稳定介电响应和明显磁损耗行为。碳化温度可调控复介电常数、复磁导率及阻抗匹配状态，使材料在低厚度下获得高效微波衰减。二维片状结构、丰富界面及金属纳米颗粒共同作用，实现介电与磁损耗协同增强，结果显示，P-CoNi/C-600在厚度仅1.7 mm时达到-51.9 dB最低反射损耗。本研究为低厚度、高强度吸波材料的设计提供了新策略。

Abstract

Traditional metal and ferrite microwave absorbing materials are limited by high density

excessive thickness

and insufficient absorption intensity

restricting their effectiveness in protecting modern electronic devices from electromagnetic interference. Two-dimensional (2D) sheet-like Hofmann-type metal-organic frameworks (MOFs) possess ordered crystal structures

well-defined interfaces

and facile fabrication processes

providing a promising platform for designing high-performance microwave absorbers. In this study

Co[Ni(CN)₄] MOF was employed as a precursor to fabricate 2D CoNi/C composites through a controlled carbonization strategy. During carbonization

NiCo nanoparticles were uniformly embedded within a continuous carbon matrix

resulting in abundant heterointerfaces

stable dielectric response

and pronounced magnetic loss behavior. The carbonization temperature was systematically optimized to tune the complex permittivity

complex permeability

and impedance matching

enabling effective microwave attenuation at minimal thickness. Detailed structural characterization revealed that the 2D morphology and porous carbon framework facilitate formation of conductive networks and interface polarization

while metallic nanoparticles contribute to magnetic resonance

collectively enhancing the synergistic interaction between dielectric and magnetic losses. Electromagnetic measurements demonstrated that the P-CoNi/C-600 sample exhibits a minimum reflection loss of –51.9 dB at a thickness of 1.7 mm and maintains a broad effective absorption bandwidth

highlighting the efficiency of low-thickness microwave absorption. This work elucidates the cooperative dielectric–magnetic loss mechanism in Hofmann MOF-derived CoNi/C composites and provides a practical strategy for the rational design of lightweight

high-performance microwave absorbing materials for advanced electromagnetic protection applications.
