Abstract
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%.

Monolayer or several-layer black phosphorus (BP), named black phosphorene or phosphorene, is a type of two-dimensional (2D) nanomaterial with distinct physical/chemical properties due to the dimensionality effect
For further testifying the structure, X-ray diffraction (XRD) was carried out on the BP powders, as shown in Figure 2b, which indicated that the BP had a good crystallinity without
