Abstract | Developing mechanically strong TPU-based nanocomposites with integrated fire resistance, smoke suppression and electromagnetic interference (EMI) shielding performances is a great challenge. Herein, we designed a mechanically tough and fire safe thermoplastic polyurethane/silicon wrapped ammonium polyphosphate polyphosphazene functionalized titanium carbide/carbon fiber fabric (TPU/SiAPZ@M/CF) nanocomposite with good EMI shielding properties. The as-prepared TPU/SiAPZ@M nanocomposites showed excellent fire safety. For example, the peak of heat release rate, total heat release and total smoke release of TPU/SiAPZ@M-4.0 were significantly decreased by 77.9 %, 46.7 % and 51.6 %, respectively, compared to those of pure TPU. Additionally, the tensile strength of TPU/SiAPZ@M-4.0/CF reached 55.1 MPa. Furthermore, this composite demonstrated acceptable EMI shielding performance, with an EMI shielding effectiveness of 27.4 dB, surpassing the commercial demand of 20 dB. Therefore, the combination of superior fire safety, high mechanical strength and excellent EMI shielding performances makes the hierarchical TPU/SiAPZ@M/CF nanocomposites promising applications in various fields. |
