enhancing fire safety of epoxy resin with bio-based metal-organic frameworknanoparticles derived from adenine

Heavy metal pollution, with its severe health consequences, has intensified environmentalconcerns. developing effective adsorbents for eliminating these hazardous metals from aquaticecosystems is essential. this study introduces adenine as an efficient adsorbent to remove zincions, paving the way for bio-based metal-organic framework (biomof) nanoparticles. thesenanoparticles enhance char formation in epoxy (ep) composites, as revealed by thermogravimetricanalysis. notably, the ep composite with 8.0 wt% biomof attains a remarkable 31.0% limitingoxygen index (loi) and ul-94 v-0 rating, indicating excellent fire resistance. furthermore, thiscomposite experiences significant reductions of 56.3% in peak heat release rate (phrr), 50.5%in total heat release (thr), and 72.0% in smoke production rate (spr). moreover, it exhibitselevated glass transition temperature and enhanced tensile strength. this innovative work presentsa sustainable approach, repurposing adsorbent waste for crafting fire-safe ep resins
