Synthesis and surface modification of nanophosphorous-based flame retardant agent by continuous flow hydrothermal synthesis

- Surface-modified Ca5(OH)(PO4)3 (HA) nanoparticles were prepared via continuous hydrothermal method.
- A self extinguishing multicomponent epoxy nanocomposite was synthesized at a solid load <10 wt%.
- Synergism between solid loading of HA retardant and a conventional intumescent was investigated.
