Synergistic flame retardancy of MIL‐88B‐Fe metal–organic framework with aluminum diethyl hypophosphite in epoxy resin

Journal of Vinyl and Additive Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Abstract Four metal–organic frameworks (MOFs), namely MIL‐88B‐Fe, MIL‐53‐Fe, Co‐MOF, and Ni‐MOF, were successfully prepared using polyethylene terephthalate (PET) waste as the raw material. The structure morphology of MOFs characterized scanning electron microscopy (SEM) X‐ray diffraction (XRD). Subsequently, synergistic flame retardancy these with aluminum diethylphosphinate (ADP) in epoxy resin (EP) was compared. MOFs, particular exhibited significant when used combination ADP. When addition amount MIL‐88B‐Fe ADP EP 4% to weight ratio at 1:19, flame‐retardant EP, EP/Fe88B‐ADP‐2:38, achieved a high limiting oxygen index (LOI) value 34.2%. Thermogravimetric analysis (TGA) results indicated that residual carbon EP/Fe88B‐ADP‐2:38 increased by approximately 6.6% compared pure EP. Additionally, peak heat release rate (PHRR) decreased 30.2% also demonstrated excellent smoke suppression, 16.5% decrease total production (TSP) These studies have provided new insights into efficient utilization PET waste. retardant, composed waste‐derived ADP, can enhance while preserving EP's mechanical properties. Highlights showed 1:19 reached UL‐94 V‐0 rating. MIL‐88B‐Fe/ADP retardant hardly
