摘要

高效的电磁干扰（EMI）屏蔽材料对于便携式硬件和柔性电子产品至关重要，在这些领域，机械耐用性经常带来挑战。在这里，热塑性聚氨酯优异的耐磨性和灵活性被用来为电磁干扰设备提供“保护层”。采用涂布法制备了碳纳米管/纤维素/热塑性聚氨酯（CNT/纸/TPU）三层复合纸。CNTs、纤维素和TPU之间的强氢键确保了牢固的整合。该复合材料厚度为0.54 mm，电导率为1040 S/m，具有69.0 dB的优异EMI屏蔽效果。它具有防水、抗溶剂、抗弯曲和抗摩擦的耐久性，同时保持屏蔽性能。此外，其优异的机械性能和抗疲劳性能显著提高设备寿命。因此，预计这项工作将为开发具有优异耐用EMI屏蔽性能的材料开辟一条简单的策略。

High-Durability Cellulose-Based Composite Paper with Superior Electromagnetic Interference Shielding

Highly efficient electromagnetic interference (EMI) shielding materials are critical for portable hardware and flexible electronics, where mechanical durability often poses challenges. Here, the excellent wear resistance and flexibility of thermoplastic polyurethane are utilized to provide a “protective layer” for EMI equipment. A carbon nanotube/cellulose/thermoplastic polyurethane (CNT/paper/TPU) composite paper with a three-layer structure was prepared using a coating method. Strong hydrogen bonds between CNTs, cellulose, and TPU ensured robust integration. The composite, with a thickness of 0.54 mm and conductivity of 1040 S/m, achieved exceptional EMI shielding effectiveness of 69.0 dB. It demonstrated durability against water, solvents, bending, and friction while maintaining shielding performance. Furthermore, its excellent mechanical properties and fatigue resistance significantly enhance equipment lifespan. Therefore, it is expected that this work will open a simple strategy for developing materials with excellent durable EMI shielding properties.
