Construction of fullerene grafted magnolol-based phosphonate and its regulation for the combustion behavior of intumescent flame-retardant polypropylene

Key Points

• Intumescent flame-retardant polypropylene shows improved combustion behavior with fullerene grafted phosphonate.
• The treatment effectively reduces peak heat release rate by 25%, compared to untreated materials.
• Experimental assessment using combustion analysis reveals the effectiveness of the grafted phosphonate structure.
• The study supports the potential for safer flame-retardant materials in industrial applications.
