Abstract
High fire hazard of thermoplastic polyurethane (TPU) has been an unavoidable obstruction on its comprehensive employment. Here, this work utilizes the physical barrier and promoting charring effect of functionalized multicomponent molybdenum diselenide/carbon nanotubes nanohybrid (HCMo) to reduce the fire hazard of TPU. Markedly suppressed heat and smoke releases can be obtained after its addition. With 3.0â¯wt% HCMo dosage, the peak heat release rate (PHRR) is decreased by 38.3%. The peak smoke production rate (PSPR) and peak specific extinction area (PSEA) values are reduced by 32.1 and 35.6%, respectively. Moreover, the toxic volatiles release is obviously inhibited after its incorporation. Furthermore, by incorporating 1.0â¯wt% HCMo, the decreased smoke density is obtained and the total yields of CO and CO2 are decreased by 13.4 and 20.0%, respectively. Overall, HCMo shows favorable suppressions function on heat, smoke and toxic gases releases, resulting in the improved fire safety of TPU.
