Summary: In this study, an epoxyfunctional cyclotriphosphazene was used for modifying polyurethane high-solid coatings. The introduction of cyclotriphosphazene resulted in improved thermal stability and flame retardancy of the coatings. The modified coatings exhibited excellent elasticity, impact resistance, and adhesion, but had relatively low hardness. The gloss and hydrophobicity of the coatings were affected by the addition of cyclotriphosphazene.

Summary: A flame retardant waterborne polyurethane with phosphorus, nitrogen and silicon units (P-N-Si-WPU) was successfully synthesized using a one-step approach. P-N-Si-WPU showed higher limiting oxygen index value and lower peak heat release rate compared to pure waterborne polyurethane. The flame retardant mechanism of P-N-Si-WPU was mainly gas phase flame retardant and condensed phase flame retardant, enhanced by the formation of a thermally stable char layer.

Summary: A novel phospho-silicon co-flame retardant material composed of montmorillonite modified black phosphorus nanosheets (MMT-BP) is synthesized. MMT-BP nanosheets improve the thermal stability, mechanical properties, and fire safety of waterborne polyurethane (WPU). The superior flame-retardancy observed in the WPU nanocomposites containing 0.4 wt% MMT-BP is attributed to the formation of an Si-O-P bond between BP and MMT during passivation and the enhanced catalytic carbonization of BP in the condensed phase.
