Owing to its intrinsic structure, thermal stability and dimension effects, black phosphorene (BP) has great potential in manufacturing advanced-performance polymer composites. However, the shortcoming of instability and re-agglomeration enables great challenges toward its application. Herein, a lanthanide metal ligand ((CF₃SO₃)₃Er) has been employed to decorate few-layer BP nanosheets. By means of density functional theory (DFT), there is a high adsorption energy of −1.49 eV in the system, which confirms a powerful adsorbing effect is existed between BP and (CF₃SO₃)₃Er. Due to the charge transfer from BP to (CF₃SO₃)₃Er molecule, the lone-pair electrons of BP are passivated, thereby the decorated BP (Er-BP) exhibits robust stability in ambient conditions and common solvents. Whereafter, the Er-BP is loading into epoxy resin (EP) to manufacture EP-based composites. The Er-BP can not only effectively enhance the dispersion of BP in EP substrate, but also catalyze the curing process of EP nanocomposites. When the amount of Er-BP in epoxy is 3.0 wt%, the residual char content is clearly improved by 75.42%, which is attributed to the coadjutant catalytic charring function between BP and (CF₃SO₃)₃Er. EP/Er-BP 3.0 sample can meet the requirement of UL-94 V-0 testing, and the limiting oxygen index (LOI) value is improved from 24.7% to 30.3%. Meanwhile, there is a 61.37% reduction in the peak heat release rate (PHRR) and a 36.68% decrease in the total heat release (THR). The smoke production rate (SPR) and total smoke production (TSP) are also decreased by 62.90% and 55.94%, respectively. Particularly, the amount of CO released per second (COP) is dramatically reduced by 74.24%, implying that the heat and smoke release has been significantly suppressed due to the production of protective char layer.

由于其固有的结构，热稳定性和尺寸效应，黑色磷烯（BP）在制造高性能聚合物复合材料方面具有巨大潜力。然而，不稳定性和再聚结的缺点使得其应用面临巨大挑战。在本文中，已经使用镧系金属配体（（CF ₃ SO ₃）₃ Er）来装饰几层BP纳米片。借助密度泛函理论（DFT），系统中的吸附能很高，为-1.49 eV，这表明BP与（CF ₃ SO ₃）₃ Er之间存在强大的吸附作用。由于电荷从BP转移到（CF ₃ SO ₃）₃Er分子使BP的孤对电子被钝化，因此修饰的BP（Er-BP）在环境条件和常用溶剂中表现出强大的稳定性。之后，将Er-BP装入环氧树脂（EP）中以制造基于EP的复合材料。Er-BP不仅可以有效地增强BP在EP基体中的分散性，而且可以催化EP纳米复合材料的固化过程。当环氧树脂中Er-BP的含量为3.0 wt％时，残余炭含量明显提高了75.42％，这归因于BP与（CF ₃ SO ₃）₃之间的共助催化炭化功能呃。EP / Er-BP 3.0样品可以满足UL-94 V-0测试的要求，极限氧指数（LOI）值从24.7％提高到30.3％。同时，峰值放热率（PHRR）降低61.37％，总放热（THR）降低36.68％。排烟率（SPR）和总排烟量（TSP）也分别降低了62.90％和55.94％。特别是，每秒释放的CO（COP）量显着减少了74.24％，这意味着由于保护性炭层的产生，显着抑制了热量和烟雾的释放。
