Hierarchical bio-based flame retardant BNNS@PA@Fe-MOFs: A nanomaterials self-assembly strategy towards reducing fire hazard of polylactic acid and improving its degradation.

As a substitute for petroleum-based polymers, polylactic acid (PLA) always attracts great interest due to its unique eco-friendly properties and versatile applications. However, the inherent high flammability and slow natural degradation are still ch…
