Fullerene decorated by iron compound (C₆₀‐Fe) is fabricated via solution reaction and characterized by transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), wide‐angle X‐ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Upon incorporating C₆₀‐Fe into high‐density polyethylene (HDPE) matrix by melt blending, the thermal and thermo‐oxidative stability of HDPE are considerably increased, the oxidative induction time (OIT) is dramatically extend. When the concentration of C₆₀‐Fe reached 5 wt%, the onset degradation temperature in air increased from 352°C to 422°C, and the OIT dramatically delayed from 4.5 to 47.8 minutes. Moreover, from microscale combustion calorimetry (MCC), C₆₀‐Fe can reduce the peak heat release rate (PHRR), heat release capacity (HRC), and total heat release (THR) values of the composites, all of which are very important parameters for evaluating the fire retardancy of a polymeric material.

铁化合物装饰富勒烯的制备及其对高密度聚乙烯热稳定性和可燃性的影响

通过溶液反应制备由铁化合物（C ₆₀ ‐Fe）装饰的富勒烯，并通过透射电子显微镜（TEM），X射线光电子能谱（XPS），广角X射线衍射（XRD），热重分析（TGA）进行表征）和差示扫描量热法（DSC）。通过熔融共混将C ₆₀ -Fe掺入高密度聚乙烯（HDPE）基体中后，HDPE的热稳定性和热氧化稳定性大大提高，氧化诱导时间（OIT）大大延长。当C ₆₀ -Fe的浓度达到5 wt％时，空气中的起始降解温度从352°C升高到422°C，OIT从4.5分钟显着延迟到47.8分钟。此外，根据微型燃烧量热法（MCC），C₆₀ -Fe可以降低复合材料的峰值热释放速率（PHRR），热释放容量（HRC）和总热释放（THR）值，所有这些对于评估聚合材料的阻燃性都是非常重要的参数。
