摘要

Ti3C2Tx MXene是一种具有高导电性和低密度的新型二维纳米材料，在高性能微波吸收方面具有很大的潜力，但由于其介电常数较高，导致其阻抗匹配较差。本研究通过将Ti3C2Tx与磁性Ni纳米颗粒混合，并将其纳入聚酰亚胺（PI）基质中形成复合材料来解决这一问题。对复合材料的结构和吸波性能进行了分析，发现当吸波量为7.5 wt%时，复合材料的吸波性能最佳。在厚度为1.2 mm时，在17.11 GHz处的最小反射损耗（RLmin）为- 51.26 dB，在1.1 mm处的最大有效吸收带宽（EAB）为5.19 GHz。这种方法为开发具有增强微波吸收能力的复合材料提供了一种有效的策略。

Ni Nanoparticle-Ti3C2Tx/PI composites with multiple wave absorption mechanisms

Ti₃C₂T_x MXene, a novel two-dimensional nanomaterial with high electrical conductivity and low density, shows great potential for high-performance microwave absorption but suffers from poor impedance matching due to its high dielectric constant. This study addresses this issue by mixing Ti₃C₂T_x with magnetic Ni nanoparticles and incorporating them into a polyimide (PI) matrix to form a composite. The composite’s structure and wave absorption properties were analyzed, revealing optimal performance at 7.5 wt% wave absorbent content. It achieved a minimum reflection loss (RL_min) of −51.26 dB at 17.11 GHz with a thickness of 1.2 mm and a maximum effective absorption bandwidth (EAB) of 5.19 GHz at 1.1 mm. This approach offers an effective strategy for developing composite materials with enhanced microwave absorption capabilities.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
