A large number of toxic fumes evolved from polymeric materials are a great threat to human evacuation. The aim of this work is to dramatically reduce the generation of smoke and toxic gaseous products upon polymers burning. A highly efficient titanium carbide/nano-copper (Ti3C2Tx/Nano-Cu) hybrid smoke suppressant was synthesized by interficial adhesion and then incorporated into thermoplastic polyurethane (TPU) to fabricate TPU nanocomposites. The Ti3C2Tx/Nano-Cu hybrid was homogeneously dispersed in the TPU matrix and showed a strong interfacial interaction with the TPU host. Introducing the Ti3C2Tx/Nano-Cu hybrid into TPU led to enhanced high-temperature stability. Furthermore, the smoke production rate, CO production rate and total CO yield of the TPU nanocomposite containing 2 wt% Ti3C2Tx/Nano-Cu hybrid decreased by 66.7%, 51.8% and 52.9%, respectively, compared with those of pure TPU. The reduced fire hazards of the TPU were due to the physical barrier, the catalytic charring and the chemical conversion of Ti3C2Tx/Nano-Cu hybrid.

高效 MXene/Nano-Cu 抑烟剂可降低热塑性聚氨酯的火灾危险

聚合物材料产生的大量有毒烟雾对人类疏散构成巨大威胁。这项工作的目的是显着减少聚合物燃烧时产生的烟雾和有毒气体产物。一种高效的碳化钛/纳米铜(Ti 3 C 2 T x /Nano-Cu)杂化抑烟剂通过表面粘附合成,然后掺入热塑性聚氨酯(TPU)中以制备TPU纳米复合材料。Ti 3 C 2 T x /Nano-Cu 杂化物均匀地分散在 TPU 基体中,并显示出与 TPU 主体的强界面相互作用。介绍 Ti 3 C 2 T x/Nano-Cu 杂化到 TPU 中可提高高温稳定性。此外,含 2 wt% Ti 3 C 2 T x /Nano-Cu 杂化材料的 TPU 纳米复合材料的烟气产生率、CO 产生率和 CO 总产率分别下降 66.7%、51.8%和 52.9%纯TPU。TPU 的火灾危险性降低是由于 Ti 3 C 2 T x /Nano-Cu 杂化物的物理屏障、催化炭化和化学转化。
