Recent Progress in Improving Fire Retardancy of Polymers Via Combined Catalysis: Polycarbonate by the Combination of Nanosized Carbon Black and Ni2O3

摘要：

　　Catalyzing carbonization of polymer itself to form a protective carbonaceous layer has attracted tremendous interest in the flame retardancy of polymers.In this study, the combined catalyst (nanosized carbon black (CB) and Ni2O3), was found to efficiently catalyze the carbonization of polycarbonate (PC), resulting in greatly improved its flame retardancy.The LOI was 31.2%, and UL-94 reached to V0, as well as the PHRR reduced approximately 50%.The flame retardancy mechanism was attributed to the synergistic effect of the combined catalysts on catalyzing carbonization of PC, which could enhance the carbon skeleton of PC to form better carbon layer structurc with small closed-cells, resulting in drastically enhanced barrier effect.
