Abstract

Highlights

The large-scale, high-strength, super-tough, and multifunctional nacre-like heterocyclic aramid (HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite papers were fabricated using the in-situ assembly of PPy onto the HA/MXene hydrogel template.
The "brick-and-mortar" layered structure and abundant hydrogen-bonding interactions among MXene, PPy, and HA respond cooperatively to external stress and effectively increase the mechanical properties of HMP nanocomposite papers.
The templating effect from HA/MXene was utilized to guide the assembly of conducting polymers, leading to high electrical conductivity and outstanding electromagnetic interference shielding performance.

通过杂环芳纶/二甲苯模板辅助原位聚吡咯组装实现电磁干扰屏蔽的多功能珍珠母状纳米复合材料论文

通过在HA/MXene水凝胶模板上原位组装聚吡咯（PPy），制备了大尺度、高强、超韧、多功能珍珠状杂环芳纶（HA）/MXene@聚吡咯（PPy）（HMP）纳米复合纸。MXene、PPy和HA之间的 "砖墙式 "分层结构和丰富的氢键相互作用对外部应力产生了协同反应，有效地提高了HMP纳米复合纸的机械性能。利用HA/MXene的模板效应引导导电聚合物的组装，从而获得了高导电性和出色的电磁干扰屏蔽性能。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
