Fabrication of Fullerene Anchored Reduced Graphene Oxide Hybrids and Their Synergistic Reinforcement on the Flame Retardancy of Epoxy Resin.

ABSTRACT: A C₆₀-PEI-rGO hybrid was prepared by incorporating the fullerene (C₆₀) on the surface of PEI-modified reduced graphene oxide (rGO) and then used to modify the epoxy (EP) resin. Subsequently, the structure of GO and C₆₀-PEI-rGO hybrid were well characterized, showing that the C₆₀ was homogenously anchored on the surface of PEI-rGO. The flame retardancy, mechanical properties, and thermal stability of as-prepared C₆₀-PEI-rGO/EP nanocomposites were systematically investigated. Results show that the C₆₀-PEI-rGO hybrid exhibits high flame retarding efficiency for EP. Specifically, the time to ignition of epoxy increases from 68 to 89 s with the addition of 1.0 wt% C₆₀-PEI-rGO, which are unusual in polymer nanocomposite
