Bimetallic Effect of Hybrid Flame Retardant on Flame Retardant Performance in Polypropylene

curves further indicate a higher degree of graphitization of the carbon layer in the combustion residue, which should be ascribed to the bimetallic effect. Therefore, this work puts forward a strategy to achieve high-performance PP composites with excellent flame retardant properties, which exhibit huge applications in electrical appliances and energy vehicles.
