“…With the addition of 22% IFR, the LOI value of PS‐22%IFR sample is increased to 27.2% and burning duration is decreased to 137 s. With the increased IFR content, the LOI value rises to 27.7%, the combustion time is further shortened to 52 s (PS‐27%IFR). One can see from Table 2 and Figure 4 that all the PS‐IFR samples cannot pass any ratings in UL‐94 tests because of the molten dripping problem, which is consistent with the published results, 34 showing the limited flame retardant efficiency of traditional IFR system.…”

In this work, a metal organic framework (Fe‐MOF) with the effect of absorbing toxic gases and good compatibility was synthesized by chelating a novel organic ligand contained carbonization groups (reacted by tris(hydroxymethyl) aminomethane and 1,4‐piperazine dialdehyde) with iron salt. Then, it was used as the synergist to improve the efficiency of intumescent flame retardant (IFR) within polystyrene (PS) substrate. With the addition of 20% IFR and 2% Fe‐MOF, the obtained PS composites exhibited a limiting oxygen index (LOI) value of 28.3% and a UL rating of V‐0. Moreover, the peak heat release rate (pHRR), total heat release (THR), and total smoke production (TSP) of PS composites were decreased by 77.6%, 35.2%, and 33.7%, respectively. According to the mechanism analysis, it was found that Fe‐MOF mainly acted in the condensed phase, contributing to the existence of dense char residues with the presence of IFR system. In addition, the good compatibility of organic ligand in Fe‐MOF with PS substrate could partially alleviate the deterioration of mechanical properties due to the addition of IFR. For PS‐20%IFR/2%Fe‐MOF, the impact strength was improved from 1.7 kJ/m2 (PS‐22%IFR) to 2.2 kJ/m2, the tensile strength was also increased from 21.3 MPa (PS‐22%IFR) to 22.4 MPa.

“…The other is that the PPO has a certain degree of self‐extinguishing properties, but the addition of combustible PS/HIPS resin significantly reduces the flame retardant properties of PPO blends. As it was reported, 20 PPO with a 60 wt% loading of HIPS could not reach V‐0 rating in UL‐94 test, and the LOI value just reached 21.7%.…”

“…Even though PPO possesses many promising properties and a competitive price, the melt viscosity of PPO is extremely high due to its chain rigidity. 19 In order to increase the fluidity of PPO, various polymers such as polystyrene (PS), 20,21 high impact PS (HIPS), [22][23][24] polyamide (PA), 25 poly(butylene terephthalate) (PBT), 26 and liquid crystal polymers (LCP) 27 have been introduced to reduce its viscosity. A direct melt blending of two polymers generally results in poor mechanical properties because of poor dispersion and lack of adequate interfacial adhesion.…”

Polymeric foam with high expansion ratio, well-defined cell structure, and excellent flame retardant properties is essential for broadening its applications. Polyphenylene oxide (PPO) is a kind of cost-effective engineering plastic with excellent flame retardancy, anti-dripping behavior, and good mechanical strength, but suffers from its poor processability. In this study, microcellular PPO composite foams were fabricated by applying a solid-state foaming technology using compressed CO 2 as the blowing agent. High-impact polystyrene (HIPS) phase was introduced with the aim to improve the fluidity and foaming ability of PPO composites. It was interesting to find that the 18-48% HIPS loading significantly increased the expansion ratio, that is, 1.8-3.3 versus, 10.8-14.3, and broadened the optimum foaming temperature of PPO composite foams, attributing to the miscible character between PPO and HIPS and excellent foaming ability of HIPS. Furthermore, the as-prepared PPO/HIPS composite foams exhibited high limited oxygen index (LOI) of 22.0-29.9%, low

“…As a typical sub-factor in mechanochemistry [ 36 ], ball milling has been developed for crushing, mixing, and reacting, due to the impact and shear forces generated by high-speed rotation and high-temperature surroundings [ 37 , 38 , 39 , 40 ]. It is widely used in fabricating flame retardants, for its superior properties of easy processing, low cost, and large-scale production [ 39 ].…”

To meet the growing needs of public safety and sustainable development, it is highly desirable to develop flame-retardant polymer materials using a facile and low-cost method. Although conventional solution chemical synthesis has proven to be an efficient way of developing flame retardants, it often requires organic solvents and a complicated separation process. In this review, we summarize the progress made in utilizing simple ball milling (an important type of mechanochemical approach) to fabricate flame retardants and flame-retardant polymer composites. To elaborate, we first present a basic introduction to ball milling, and its crushing, exfoliating, modifying, and reacting actions, as used in the development of high-performance flame retardants. Then, we report the mixing action of ball milling, as used in the preparation of flame-retardant polymer composites, especially in the formation of multifunctional segregated structures. Hopefully, this review will provide a reference for the study of developing flame-retardant polymer materials in a facile and feasible way.
