Ultrafine nickel nanocatalyst-engineering of an organic layered double hydroxide towards a super-efficient fire-safe epoxy resin via interfacial catalysis

An ultrafine Ni(OH)₂ nanocatalyst was surface-assembled on the organically modified layered double hydroxide (LDH-DBS) to prepare nanohybrid LDH-DBS@Ni(OH)₂. A mere 3 wt% of LDH-DBS@Ni(OH)₂ imparted epoxy resin with UL-94 V-0 rating and a 60.6% reduction of peak heat release rate due to the interfacial catalysis.
