Preparation of cobalt-based metal organic framework and its application as synergistic flame retardant in thermoplastic polyurethane (TPU)

Waste to resource: preparation of an efficient adsorbent and its sustainable utilization in flame retardant polyurethane composites

“…21,31 Aer MH adsorbs phosphate, the MH-P contains two components: MH and inorganic phosphate, so it has a different ame retardant effect, in comparison with MH, and thereby leading to the variation of combustion data. On the other hand, as a metal organic frame material, MOF has ame retardant effect, and also can improve the interface interaction between the ame retardant and polymer matrix, 44 thereby improving the ame retardant efficiency of the ame retardant. In addition, the introduction of MOF made the ame retardant aer adsorption of phosphorus (MH@MOF-P) present a porous structure, which can improve the ame retardancy through "labyrinth effect".…”

“…40 Secondly, in the process of combustion, MOF can not only absorb smoke, but also produce metal oxides to catalyze the carbonization of polymers. [41][42][43][44][45][46][47] Therefore, it is a promising strategy to modify magnesium hydroxide with MOF.…”

Covalently functionalized graphene oxide wrapped by silicon–nitrogen-containing molecules: preparation and simultaneous enhancement of the thermal stability, flame retardancy and mechanical properties of epoxy resin nanocomposites

“…However, this view had not been proved. 33,34 Here, a Py-GC/MS test was conducted to obtain the pyrolytic products of DDM. The gas chromatography spectra of DDM and its proposed pyrolysis process are shown in Fig.…”

Improvement of thermoplastic polyurethane's flame retardancy and thermal conductivity by leaf‐shaped cobalt‐zeolitic imidazolate framework–modified graphene and intumescent flame retardant

“…19 In recent years, zeolitic imidazolate frameworks (ZIFs) containing different metal such as iron, zinc and cobalt has attracted a lot of attention in flame retardant field. 20 Such as the ZIF-8 was used as a flame retardant in polyvinyl alcohol (PVA) and their limiting oxygen index increased from 19.5% to 24.0%. 21 In addition, some studies have shown that ZIFs combined with carbon nano-inorganic has better flame retardant efficiency.…”

“…The synergistic effect of dual imidazolium polyoxometalates (POMs) and intumescent flame retardant is also evident in polypropylene composites 19 . In recent years, zeolitic imidazolate frameworks (ZIFs) containing different metal such as iron, zinc and cobalt has attracted a lot of attention in flame retardant field 20 . Such as the ZIF‐8 was used as a flame retardant in polyvinyl alcohol (PVA) and their limiting oxygen index increased from 19.5% to 24.0% 21 .…”
