Layer by layer deposition of polyethylenimine and bio-based polyphosphate on ammonium polyphosphate: A novel hybrid for simultaneously improving the flame retardancy and toughness of polylactic acid
A novel bio-based polyelectrolyte was synthesized using plant-derived resource diphenolic acid. A novel hybrid with core/shell structure was fabricated via layer-by-layer assembly method. The core/shell hybrid imparted both highly efficient flame retardancy and toughness to polylactic acid.
