Black phosphorene-waterborne polyurethane (BPWPU) composite polymer with 0.2 wt % of black phosphorene was synthesized. Scanning electron microscopy (SEM) was used to observe the morphology of phosphorene in polyurethane matrix, which indicated that the phosphorene distributes uniformly in the PU matrix. The flammability measurements were carried out to investigate the flame-resistant performances of phosphorene, which indicated that phosphorene could effectively restrict the degradation of the PU membrane. Compared by the pure WPU, the limiting oxygen index (LOI) of BPWPU increased by 2.6%, the heat flow determined by thermal analysis significantly decreased by 34.7% moreover, the peak heat release rate (PHRR) decreased by 10.3%.
合成了含0.2 wt%黑磷的黑磷-水性聚氨酯（BPWPU）复合聚合物。采用扫描电子显微镜（SEM）观察聚氨酯基体中磷烯的形态，结果表明磷烯在聚氨酯基体中均匀分布。进行了燃烧性能测试以研究磷烯的阻燃性能，结果表明磷烯可有效抑制聚氨酯膜的降解。与纯水性聚氨酯（WPU）相比，BPWPU的极限氧指数（LOI）提高了2.6%，热分析测定的热流显著降低了34.7%，此外，热释放速率峰值（PHRR）降低了10.3%。
