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 flexibility of thermoplastic polyurethane utilized to provide a "protective layer" EMI equipment. A carbon nanotube/cellulose/thermoplastic (CNT/paper/TPU) composite paper with three-layer structure was prepared using coating method. Strong hydrogen bonds between CNTs, cellulose, TPU ensured robust integration. The composite, thickness 0.54 mm conductivity 1040 S/m, achieved exceptional effectiveness 69.0 dB. It demonstrated against water, solvents, bending, friction while maintaining performance. Furthermore, its properties fatigue significantly enhance equipment lifespan. Therefore, it is expected that this work will open simple strategy developing durable properties.
