The synergism between nanoparticles and different kinds of halogen-free fire retardants leading to reduction in flammability and smoke generation of polyethylene was investigated. The composites were evaluated by thermogravimetric analysis, oxygen index test, cone calorimeter measurements, and a single-chamber test. Moreover, the semivolatile and volatile compounds evolved in the thermal degradation processes of polyethylene were determined using a steady state tube furnace and gas chromatograph with mass spectrometer. Morphological and structural characteristics as well as thermomechanical properties of the composites were characterized using various techniques including scanning electron microscopy (SEM), X-ray diffraction (XRD), and dynamic mechanical thermal analysis (DMTA). The obtained data were compared to the results received for polyethylene and polymer with bromine-containing fire retardants. The incorporation of nanofillers and halogen-free fire retardants caused a reduction in combustibility as a consequence of the formation of char.Furthermore, the presence of nanoparticles has a beneficial effect on the inhibition of dripping. The polyethylene with carbon nanotubes, zinc borate, and aluminum hydroxide exhibited better combined properties of fire behavior and production of nontoxic smoke compared to the remaining composition and reference materials.

“…Benzalkoniumchloride‐N‐methyl pryrrolidine‐fullerene (BEN‐(C 60 ‐O)) were designed and synthesized by Tsai et al, which could increase the flame retardancy of EP when cooperated with the functionalization of montmorillonite type clay (CL88). The introduction of BEN‐(C 60 ‐O) enlarged the layer space of montmorillonite, made the EP/BEN‐(C 60 ‐O)‐CL88 composite achieve V1 rating in the UL‐94 vertical burning testing and the LOI value reach 30.…”

At present, the application of fullerene in polymer materials has become an attractive issue. Fullerene can enhance the thermal and flame-retardant properties of polymers due to its high capacity to trap free radicals. Fullerene also has good synergistic effect with inorganic metal flame retardant, intumescent flame retardant, brominated flame retardant (BFR), clay, carbon nanotubes, graphene oxide, and so on. In this review, the impact and mechanism of fullerene and its derivatives on the thermal and flame-retardant properties of polymeric materials are discussed. And the prospect of fullerene in flame-retardant polymer composites is also briefly introduced by analyzing the research progress in the recent years. Scheme 8.

“…According to different reinforcing materials, they are divided into paper base, glass cloth base, and metal base, which are applied to different fields. With the advancement of technology and the increasing awareness of human environmental protection, the development of new technologies such as lead‐free soldering has become more and more demanding for CCLs, including not only the thermal properties and mechanical properties of CCLs, but also green environmental protection . At present, the resin used in rigid CCLs is basically epoxy resin.…”

Using dimer acid (DA) as raw material, DA diglycidyl ester (DADGE) was synthesized and used as reactive toughening agent to prepare paper‐based copper clad laminate (p‐CCL). The factors affecting the epoxy value of DADGE and the effect of the resin on the gelation time were studied. The effects of the epoxy value and the addition amount of DADGE on the solderleaching resistance, flammability, water absorption, bending strength, and impact strength of the p‐CCL were discussed. The results showed when the molar ratio of DA to ECH was 1:8 and the molar ratio of DA to sodium hydroxide was 1:1.6, the epoxy value of DADGE reached the maximum value of 0.23 mol/100 g. The DADGE can shorten the gelation time of the glue. The p‐CCL meets the performance of the IPC‐TM‐650 standard. And when the addition amount of DADGE is less than 12 wt %, the flammability of the p‐CCL reaches UL94V‐0 level. The p‐CCL prepared by adding 6 wt % of DADGE with 0.08 mol/100 g epoxy value has the best comprehensive performance, its toughness and rigid are comparable to those of p‐CCL with 12 wt % of commercially available high performance toughening agents and it has higher solderleaching resistance. © 2019 Wiley Periodicals, Inc.
