Mitigation the release of toxic PH3 and the fire hazard of PA6/AHP composite by MOFs

Recent Progress on Metal–Organic Framework and Its Derivatives as Novel Fire Retardants to Polymeric Materials

“…On the contrary, many MOFs showed similarity exhibiting capacity to lower the fire hazards such as suppress of smoke, toxic CO and PH 3 which are reported in different polymer matrixes such as EP, PS and PA6 [ 33 , 41 , 60 ]. The 22.8%, 30%, and 28% reductions of TSP with the addition of only 2 wt% ZIF-8 [ 61 ], UiO66-NH 2 [ 44 ] and ZIF-67 [ 62 ] for EP composites were reported.…”

“…The addition of 4% Zr-MOF imparts polycarbonate (PC) 48% reduction in pHRR and UL-94 V0 rating. The unsaturated Zr metal site made MOF possess catalytic oxidation and char formation ability[33].On the contrary, many MOFs showed similarity exhibiting capacity to lower the fire hazards such as suppress of smoke, toxic CO and PH 3 which are reported in different polymer matrixes such as EP, PS and PA6[33,41,60].

Intumescent-Grafted Bamboo Charcoal: A Natural Nontoxic Fire-Retardant Filler for Polylactic Acid (PLA) Composites

“…The flame retardancy of the material was significantly improved, indicating that coaddition of a purpose-designed flame retardant is necessary. A disadvantage of coadding AHP was that the total required amount of the filler and flame retardant significantly reduced the flexural properties of the PLA composite. , Toxic gases such as PH 3 were detected from the combustion of the composites containing AHP fire retardant, which can cause health and contamination concerns when the materials are exposed to fire. , …”

Comparative Study on the Flame Retardancy and Retarding Mechanism of Rare Earth (La, Ce, and Y)-Based Organic Frameworks on Epoxy Resin

“…Moreover, the nanoscale metal ions/clusters in MOFs play an important role in improving the FR and smoke suppression performances. Up to now, several metal centers have been selected to research the MOF-derived FRs, such as Co, 7 − 9 Zn, 10 − 12 Zr, 13 − 15 Al, 16 , 17 Fe, 18 − 20 Cu, 21 , 22 Ni, 23 − 25 Sn, 26 and Mo. 27 Hu et al have found that 2D layered and 3D block MOFs combining common transition metals (such as Fe, Co, Zr, and Ni) and rigid organic complexes showed better flame retardancy with less dosage.…”

Up to now, several metal centers have been selected to research the MOF-derived FRs, such as Co, − Zn, − Zr, − Al, , Fe, − Cu, , Ni, − Sn, and Mo . Hu et al have found that 2D layered and 3D block MOFs combining common transition metals (such as Fe, Co, Zr, and Ni) and rigid organic complexes showed better flame retardancy with less dosage. − ,,, Zheng et al reported that Co-, Zn-, and Fe-MOFs can effectively reduce the heat release rate (HRR), smoke production rate (SPR), and CO production (COP) of epoxy (EP) composites .…”
