Abstract

Highlights

The Janus-type multifunctional ultra-flexible polytetrafluoroethylene-carbon nanotube-Fe₃O₄/MXene (FCFe/M) membranes were fabricated via a shear-induced in situ fibrillation technique followed by vacuum-assisted filtration.
Thanks to the strategic distribution of the MXene conductive reflection layer and the silk-like FCFe electromagnetic wave’s absorption layer, the membranes achieve robust electromagnetic interference shielding and effective antireflection through the absorption-reflection-reabsorption mechanism.
The membranes exhibit exceptional thermal management performance, including efficient heat dissipation and electrothermal/photothermal conversion capabilities, further enhancing their promising potential for applications in flexible wearable technologies.

用于增强EMI屏蔽和热管理的多功能双面结构聚四氟乙烯-碳纳米管- fe3o4 /MXene膜

采用剪切诱导原位纤颤技术和真空辅助过滤法制备了janus型多功能超柔性聚四氟乙烯-碳纳米管- fe3o4 /MXene （FCFe/M）膜。由于MXene导电反射层和丝状FCFe电磁波吸收层的战略性分布，膜通过吸收-反射-重吸收机制实现了强大的电磁干扰屏蔽和有效的抗反射。该膜具有出色的热管理性能，包括高效的散热和电热/光热转换能力，进一步增强了其在灵活可穿戴技术中的应用潜力。

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.
