Synergistic Flame Retardancy and Smoke Suppression in Flexible PVC Enabled by Magnesium Hydroxide With a Dual‐Layer Coating and Fe( OH ) 3 Decoration
To improve the flame retardancy and smoke suppression of magnesium hydroxide (MH) in flexible PVC, a hierarchical flame retardant (MH‐P2@Fe) was designed via dual‐layer coating of polydopamine (PDA) and polydichlorophosphazene (PDCP) followed by Fe(OH) 3 loading. The introduction of Fe(OH) 3 enhanced the therma...
