AI Technical Summary
While existing technologies improve the flame retardant properties of polylactic acid (PLA), they often have an adverse effect on its mechanical properties, and its flammability limits its application in fields such as electronic product packaging and the automotive industry.
By using the nano flame retardant N-MX@C, COFs are combined with aminosilane-modified MXene through interfacial assembly to prepare a flame-retardant polylactic acid composite material with both good flame retardant and mechanical properties. It can also be physically mixed with phosphorus and nitrogen-rich organic flame retardants to further enhance the flame retardant effect.
It significantly improves the flame retardant and mechanical properties of polylactic acid, reduces the heat release rate and smoke emission during combustion, while maintaining or improving the tensile strength and oxygen index of the material.
