A dopamine‐triazine compound (TTD) was synthesized by using dopamine and cyanuric chloride. The TTD and ammonium polyphosphate (APP) were combined to improve the flame retardancy of thermoplastic polyurethane (TPU). The flame retardancy, thermal stability and mechanical properties of TPU blends were investigated. TPU containing 8 wt% APP displays a UL‐94 V0 rating and a limiting oxygen index (LOI) of 30.0 vol%. When APP and TTD are combined at a ratio of 7/1 (wt%/wt%), only 5 wt% flame retardant is needed to endow TPU with a UL‐94 V0 rating, suggesting that a good synergistic effect exists between APP and TTD on enhancing flame retardancy of TPU. In addition, TTD reduces the heat release rate of TPU, suppresses the smoke and toxic gas release and promotes the formation of an intumescent char layer with few defects during combustion. In addition, TTD improves the tensile properties of TPU/APP blends.

Thermoplastic poly(ether ester) elastomer (TPEE) is a highly flammable material with severe melt‐dropping, which greatly limits its range of applications. Here, black phosphorus nanosheets (BPs) and aluminum diethylphosphinate (ADP) were used to improve the fire safety of TPEE for the first time. Results demonstrated that ADP/BPs as a synergistic combination exhibits good dispersity and excellent flame retardancy, also has minimal negative effects on the mechanical performances of the TPEE composites. By comparing TPEE/ADP‐22 and TPEE/ADP‐10/BPs‐4, the introduction of BPs significantly reduced the addition of ADP while keeping the material at the higher vertical burning grade, ~54.5% reduction in ADP usage. Compared with neat TPEE, TPEE/ADP‐10/BPs‐4 fulfilled V‐0 level, avoided dripping, and the limiting oxygen index value increased to 34.0%. Moreover, TPEE/ADP‐10/BPs‐4 performed the best in cone calorimetry test, both the peak heat release rate and total heat release reduced the largest, by 44.2% and 25.3%, respectively. The detailed studies of the flame‐retardant mechanism found that ADP/BPs showed the fire‐retardant impact of the condensed phase and gaseous phase. This work expands BPs in the flame‐retardant application and could facilitate to prepare the anti‐dripping flame‐resistant TPEE.Highlights BPs as an efficient flame retardant were added into TPEE for the first time. ADP/BPs as a synergistic combination has an excellent fire‐retardant effect. The introduction of BPs significantly reduced the addition of ADP. TPEE/ADP‐10/BPs‐4 showed the highest FPI and the lowest FGI. ADP/BPs has lowest negative effects on the mechanical performances of matrix.
