“…Meanwhile, the solution mixing begins with the dispersion of the additives in a polymeric solution followed by a controlled solvent evaporation and a composite film casting [ 52 ]. The organic and inorganic compounds, multi-component formulations, and a range of nanomaterials are used as the additive FRs for different sub-classes of styrenic polymers [ 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 ...…”

“…The latest reports describe the processes when AP was added along with other compounds, with the purpose of lowering the loadings of the FR and to enhance the fire-retarding efficiency [ 67 , 68 , 69 , 70 , 71 ]. The study conducted by Zhu et al (2018) described the incorporation of expandable graphite (EG) in combination with AP for preparing fire-retarded styrenic composites, with the AP/EG content being fixed at 15 wt% [ 67 ].…”

“…The aluminium hypophosphite can also be used with a two-dimensional material such as carbon nitride (g-C 3 N 4 ), which was mentioned earlier. Zhu et al (2017) proposed the modification of g-C 3 N 4 with diethylphosphinic acid oligomers through hydrogen bonding, which was followed by the synthesis of a g-C 3 N 4 /organic aluminium diethylhypophosphite hybrid (g-C 3 N 4 /DAHPi) to improve not only the fire retardance but also the distribution of the graphitic material in the polymer matrix [ 69 ]. Similarly, g-C 3 N 4 –organic aluminium hypophosphite (g-C 3 N 4 /OAHPi) hybrid was prepared using two different phosphorus compounds: phenyldichlorophosphate (PDCP, Figure 9 a) and bicholorophenylphosphine oxide (BPOD, Figure 9 b) [ 70 ].…”

Polystyrene, despite its high flammability, is widely used as a thermal insulation material for buildings, for food packaging, in electrical and automotive industries, etc. A number of modification routes have been explored to improve the fire retardance and boost the thermal stability of commercially important styrene-based polymeric products. The earlier strategies mostly involved the use of halogenated fire retardants. Nowadays, these compounds are considered to be persistent pollutants that are hazardous to public and environmental health. Many well-known halogen-based fire retardants, regardless of their chemical structures and modes of action, have been withdrawn from built environments in the European Union, USA, and Canada. This had triggered a growing research interest in, and an industrial demand for, halogen-free alternatives, which not only will reduce the flammability but also address toxicity and bioaccumulation issues. Among the possible options, phosphorus-containing compounds have received greater attention due to their excellent fire-retarding efficiencies and environmentally friendly attributes. Numerous reports were also published on reactive and additive modifications of polystyrene in different forms, particularly in the last decade; hence, the current article aims to provide a critical review of these publications. The authors mainly intend to focus on the chemistries of phosphorous compounds, with the P atom being in different chemical environments, used either as reactive, or additive, fire retardants in styrene-based materials. The chemical pathways and possible mechanisms behind the fire retardance are discussed in this review.

“…When the content of g-C 3 N 4 in CNAPP was 20%, the best flame retardant effect was obtained (Figures 9 and 10). g-C 3 N 4 /organic aluminum diethylhypophosphites (CDAHPI) hybrids have also been synthesized by salification reactions [233]. PS composites were then prepared by a melt blending method.…”

Polymer materials are ubiquitous in daily life. While polymers are often convenient and helpful, their properties often obscure the fire hazards they may pose. Therefore, it is of great significance in terms of safety to study the flame retardant properties of polymers while still maintaining their optimal performance. Current literature shows that although traditional flame retardants can satisfy the requirements of polymer flame retardancy, due to increases in product requirements in industry, including requirements for durability, mechanical properties, and environmental friendliness, it is imperative to develop a new generation of flame retardants. In recent years, the preparation of modified two-dimensional nanomaterials as flame retardants has attracted wide attention in the field. Due to their unique layered structures, two-dimensional nanomaterials can generally improve the mechanical properties of polymers via uniform dispersion, and they can form effective physical barriers in a matrix to improve the thermal stability of polymers. For polymer applications in specialized fields, different two-dimensional nanomaterials have potential conductivity, high thermal conductivity, catalytic activity, and antiultraviolet abilities, which can meet the flame retardant requirements of polymers and allow their use in specific applications. In this review, the current research status of two-dimensional nanomaterials as flame retardants is discussed, as well as a mechanism of how they can be applied for reducing the flammability of polymers.

A new type of elastomeric composite containing natural rubber (NR) and graphitic carbon nitride (g-C 3 N 4 ) has been successfully prepared with the reinforced property. The reinforcing effect of g-C 3 N 4 in NR composites was examined by cure, mechanical, morphological, and swelling studies. Besides, epoxidized NR with 50-mol % epoxy level (ENR-50) was used as a compatibilizer to enhance the hydrophilic g-C 3 N 4 filler capacity for hydrophobic NR composites. At the same filler load level, the mechanical properties of NR/g-C 3 N 4 composites, such as tensile strength and tensile modulus, were consistently increased with increased ENR-50 content. To note, the ENR compatibilized composites have shown better-reinforced performance, which has been attributed to the hydrogen bonding interactions between the uncondensed amine groups in g-C 3 N 4 and the polar groups in ENR. We believe that these newly prepared NR composites based on g-C 3 N 4 as nonblack filler and ENR-50 as compatibilizer can find potential applications in modern day rubber research.
