A method of supercritical CO2 fluid extraction gas chromatography-mass spectrometry (GC-MS) was developed for the determination of 2 novel brominated flame retardants (BB-153 and TBECH)) in flexible polyurethane foam. The optimum conditions as follows: extraction temperature: 60°C, pressure:30Mpa, CO2 mass flow rate: 8g/min ,flow rate of methanol entrainer: 3mL/min and extraction time: 60min. The calibration curves were linear in the range of 0.1~50μg/mL with correlation coefficient of 0.9995~0.9999 and detection limits (S/N=20) of 0.05μg/mL. The average recoveries of the target compounds in sample were in the range of 97.3%~98.8%(BB-153)、99.2%~105.8% (TBECH) respectively. The results showed that this method was sensitive, reliable and environmental for the determination of 2 novel brominated flame retardants (BB-153 and TBECH)) in flexible polyurethane foam.

AbstractRecent discoveries of two-dimensional transitional metal based materials have emerged as an excellent candidate for fabricating nanostructured flame-retardants. Herein, we report an eco-friendly flame-retardant for flexible polyurethane foam (PUF), which is synthesised by hybridising MXene (Ti$$_3\hbox {C}_2$$ 3 C 2 ) with biomass materials including phytic acid (PA), casein, pectin, and chitosan (CH). Results show that coating PUFs with 3 layers of CH/PA/Ti$$_3\hbox {C}_2$$ 3 C 2 via layer-by-layer approach reduces the peak heat release and total smoke release by 51.1% and 84.8%, respectively. These exceptional improvements exceed those achieved by a CH/Ti$$_3\hbox {C}_2$$ 3 C 2 coating. To further understand the fundamental flame and smoke reduction phenomena, a pyrolysis model with surface regression was developed to simulate the flame propagation and char layer. A genetic algorithm was utilised to determine optimum parameters describing the thermal degradation rate. The superior flame-retardancy of CH/PA/Ti$$_3\hbox {C}_2$$ 3 C 2 was originated from the shielding and charring effects of the hybrid MXene with biomass materials containing aromatic rings, phenolic and phosphorous compounds.
