High-strength, flexible, and multifunctional characteristics are highly desirable for electromagnetic interference (EMI) shielding materials in the field of electric devices. In this work, inspired by natural nacre, we fabricated large-scale, layered MXene/amarid nanofiber (ANF) nanocomposite papers by blade-coating process plus sol–gel conversion step. The as-synthesized papers possess excellent mechanical performance, that is, exceptional tensile strength (198.80 ± 5.35 MPa), large strain (15.30 ± 1.01%), and good flexibility (folded into various models without fracture), which are ascribed to synergetic interactions of the interconnected three-dimensional network frame and hydrogen bonds between MXene and ANF. More importantly, the papers with extensive continuous conductive paths formed by MXene nanosheets present a high EMI shielding effectiveness of 13188.2 dB cm2 g–1 in the frequency range of 8.2–12.4 GHz. More interestingly, the papers show excellent Joule heating performance with a fast thermal response (<10 s) and a low driving voltage (≤4 V). As such, the large-scale MXene/ANF papers are considered as promising alternatives in a wide range of applications in electromagnetic shielding and thermal management.

仿生、高强度、柔性 MXene/芳纶纤维用于具有焦耳热性能的电磁干扰屏蔽纸
电子设备领域的电磁干扰(EMI)屏蔽材料非常需要高强度、柔性和多功能特性。在这项工作中,受天然珍珠层的启发,我们通过刮刀涂层工艺和溶胶-凝胶转化步骤制造了大规模的分层 MXene/amarid 纳米纤维 (ANF) 纳米复合纸。合成后的纸具有优异的机械性能,即出色的拉伸强度 (198.80 ± 5.35 MPa)、大应变 (15.30 ± 1.01%) 和良好的柔韧性(折叠成各种模型而不会断裂),这归因于协同相互作用MXene 和 ANF 之间互连的三维网络框架和氢键。更重要的是,2 g –1在 8.2–12.4 GHz 的频率范围内。更有趣的是,这些论文显示出出色的焦耳热性能,具有快速热响应(<10 s)和低驱动电压(≤4 V)。因此,大型 MXene/ANF 论文被认为是电磁屏蔽和热管理领域广泛应用中有前途的替代品。
