ABSTRACT A green and environmental‐friendly flame retardant was prepared using halogen‐free zeolitic imidazolate framework‐8 (ZIF‐8) to reduce the flammability dripping behavior of polyurethane (PU). Mainly comprising phosphorus nitrogen, produced by functionalizing ZIF‐8. First, ZIF‐8 melamine (MPP) were dissolved in absolute alcohol. Microencapsulation performed –Zn 2+ group –NH 2 MPP form a novel intumescent retardant, MPP@ZIF‐8. Furthermore, silanol‐terminated PU (Si‐PU) formed through reaction isophorone diisocyanate (IPDI) with polyol 3‐aminopropyltriethoxysilane (APTS), then MPP@ZIF‐8 introduced into prepare polymer composite material. The microencapsulation verified Fourier‐transform infrared spectroscopy, scanning electron microscopy revealed that, when additive amount increased 40 wt%, high‐temperature combustion thick dense char layer. Raman spectroscopy further demonstrated that primarily effective condensed phase; an I D /I G value decreased from its initial 0.72 0.69, indicating substantial damage structure formation both gas phase promoting continuous layer releasing NH 3 H O gases, which acted as diluents. cone calorimeter test showed total heat release material 35.7 32.5 MJ/m peak rate also 910.2 591.5 kW/m . These results confirmed safety improvement proposed during fire.
