    Here, we present a multifunctional bio-based polyelectrolyte multilayer-coated hydroxyapatite (HAP@CS@LSF) as a green flame retardant through layer-by-layer inspired assembly using hydroxyapatite, chitosan, and lignosulfonate. The electrostatic interactions deposited the chitosan/lignosulfonate coating on the surface of hydroxyapatite. Subsequently, this multifunctional flame retardant was used to enhance thermal properties, flame retardancy, and mechanical properties of poly(vinyl alcohol). The addition of HAP@CS@LSF to poly(vinyl alcohol) thermally stabilized the poly(vinyl alcohol) composites and resulted in a higher char yield. Furthermore, hydroxyapatite played a critical role and generated synergies with chitosan and lignosulfonate to improve fire safety of poly(vinyl alcohol). Meanwhile, the poly(vinyl alcohol) composites exhibited superior enhancements in tensile strength than that of pure poly(vinyl alcohol).
