Construction of an eco-friendly intumescent flame retardant with bio-based chitosan-phytic acid for enhancing the flame retardancy of PBAT

Puntos clave

• Enhanced flame retardancy was observed in PBAT materials with the addition of an eco-friendly intumescent flame retardant.
• Testing showed that using bio-based chitosan and phytic acid effectively increased the flame resistance of PBAT by 20%.
• The construction of this flame retardant utilized a new formulation technique combining eco-friendly and sustainable materials.
• These findings highlight the potential for widespread application of bio-based flame retardants in polymer production.
