Abstract: A high-efficient composite of flame retardant (CFR) composed of an aluminum hydroxide (ATH) core and an aluminum phosphate (AP) flower-like shell was synthesized by an in-situ growth method, which is low cost and easy-to-handle. It has been demonstrated that flame retardancy and smoke suppression of (ethylene-vinyl acetate) EVA/CFR were enhanced compared to EVA/ATH attributed to the high-efficiency heat barrier and gas isolation of ceramic char residues mainly composed of Al2O3 porcelain agents and AlPO4 sintering aids. Thus, the novel hierarchical core-shell AlPO4@Al(OH)(3) might supersede the ATH as flame retardants.
