Overview

Randomized trial demonstrates improved flame retardant effects in biodegradable polymers, indicating safer material options.

Key Points

  • The aim is to develop effective flame-retardant biodegradable polymers to enhance fire safety.
  • Copper phosphide is coated on P/B co-doped g-C3N4 via in situ self-assembly to create PBCN@Cu3P.
  • The environmentally friendly core-shell flame retardant is developed by mixing PBCN@Cu3P with PBAT using in situ hot-melt method.
  • Flame retardant characterization and density functional theory calculations analyze interfacial electron coupling effects.
  • The peak heat release rate decreased by 22.18%, while total heat release decreased by 13.23%.
  • Fracture strength of the composite material remained above 127%.
  • Synergistic mechanisms of flame retardancy include gas-phase radical quenching and condensed-phase carbon layer enhancement.
