ZIF-8@Co-doped boronate ester polymer core-shell particles: Catalytically enhancing the nonflammability and smoke suppression of epoxy resin

Metal–Organic Frameworks Derived from Zn and p‐Hydroxybenzoic Acid for Smoke Suppression and Flame Retardation in Vinyl Resin

“…Besides safety considerations, MOFs can also enhance the mechanical properties of composites; although, the studied MOF contents tend to be low. It is necessary to employ ammonium polyphosphate (APP), [34,35] melamine, [36] borate ester polymer (BP), [37] or cardanol-based retardants [38] to achieve a V-0 rating in the UL-94 plastic flammability standard and the ideal smoke suppression effect. This may be due to the complex morphology or structural design of MOFs, which makes the synthesis process cumbersome and the mass synthesis process difficult.…”

A novel P/N/Si/Zn-containing hybrid flame retardant for enhancing flame retardancy and smoke suppression of epoxy resins

“…[19][20][21][22] The metal oxides generated by the pyrolysis of ZIF-8 can prevent harmful smoke emissions and facilitate the formation of a graphitized char layer structure during burning, thereby safeguarding the underlying polymer. 23,24 Li et al 25 synthesized a core-shell ame retardant named ZIF-8@BP-Co using ZIF-8 as the core and Co 2+ -doped borate polymer (BP) as the shell layer. Upon introducing 7.0 wt% ZIF-8@BP-Co into EP, the composites achieved a LOI value of 29.8 ± 0.4% and successfully attained a UL-94 V-0 rating.…”

Recent advances in metal-family flame retardants: a review

“…27,28 This increases ameresistance of the polymer, and they can also reduce emission of smoke and hazardous gases during polymer burning. [29][30][31] The earliest metal-based ame retardants developed were metal hydroxides, most commonly aluminum trihydroxide (ATH) 32,33 and magnesium hydroxide (MH). [34][35][36] Jiao et al added MH to ethylene vinyl acetate (EVA) as a ame retardant to improve its re and smoke suppression capabilities.…”
