Abstract
In this paper, highly flame retardant C60/PMMA composites were prepared using an in situ polymerization method by introducing fullerene (C60) into polymethyl methacrylate (PMMA) to improve its combustion characteristics. The apparent morphologies of PMMA and C60/PMMA microspheres were observed by scanning electron microscopy (SEM), and the structure was characterized by infrared spectroscopy (FT-IR). The thermal stability and flame retardancy were characterized using a synchronous thermal analyzer, a cone calorimeter and an oxygen index tester. The results show that the maximum initial decomposition temperature of C60/PMMA-2 (prepared using C60 with a concentration of 2 mg mL−1) is 234.89 °C, which is about 59.89 °C higher than that of PMMA, and the thermal stability is the best. The limiting oxygen index of the C60/PMMA-2 composite is 21.8, which is 28.2% higher than that of pure PMMA. In addition, the peak heat release rate (PHRR) of C60/PMMA is reduced by 630.4 kW m−2 when compared with pure PMMA, which means that the flame retardant property is improved. Meanwhile, the mechanical properties of the PMMA are also improved by adding C60. In this paper, highly flame retardant C60/PMMA composites were prepared using an in situ polymerization method by introducing fullerene (C60) into polymethyl methacrylate (PMMA) to improve its combustion characteristics.![]()
