“…A carbon layer is formed on the surface of the wood sample. The carbon layer acts as a physical barrier, which can prevent heat and oxygen from penetrating into the sample [ 45 , 46 , 47 ]. However, due to the high porosity of the untreated wood sample, the carbon layer has no obvious barrier effect on the air.…”

Wood, as a naturally green and environmentally friendly material, has been widely used in the construction and decoration industries. However, the flammability of wood poses serious safety problems. To improve the fire resistance of wood, In this study, it is proposed to use calcium chloride (CaCl2) and disodium hydrogen phosphate (Na2HPO4, DSP) to impregnate wood for multiple cycles. The experimental results show that phosphate mineral precipitation can be deposited on the surface of the wood. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) are used to analyze the micromorphology of mineral precipitation and use the MIP test to analyze the treated wood pore structure. The results show that with the increase in the number of cycles, the phosphate deposited on the surface of the wood increases, and the cumulative pore volume and water absorption rate of the wood after 10 cycles are 54.3% and 13.75% lower than that of untreated wood respectively. In addition, the cone calorimeter (CONE) confirmed that the total heat release (THR) and total smoke production (TSP) of wood treated in 10 cycles have decreased by 48.7% and 54.2% respectively compared with the untreated wood. Hence, this treatment method not only improves the mechanical properties of wood. It also improves fire resistance.

“…Likewise, Nabipour et al 100 developed phosphorus‐modified methylcellulose/silica hybrid hydrogels applying 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide–itaconic acid (DOPO‐ITA), which resulted in shorter extinguishing time and lower consumption volume with respect to the ordinary water. The crosslinking of hydrogel was completed in the course of polymerization where SiO 2 nanoparticles and MC@DOPO‐ITA could react with each other.…”

Hydrogels are multifunctional engineering materials best known for their promising characteristics such as toughness, flexibility, water absorption capacity, and porosity. These features can support fire protection missions. Application of hydrogels as flame‐retardant materials is receiving much attention, such that several research and industrial projects have been devoted to design, manufacturing, and optimization of flame‐retardant hydrogels—taking a unique position among advanced multifunctional materials and strategies. Likewise, aerogels (derived from gels) due to their porous structure filled with a gas, usually air, rather than water in the case of hydrogels, have shown superior thermal insulation potential. Correspondingly, they have been used in fire and flame protection applications. In this work, the flame‐retardant hydrogels and aerogels along with mechanisms underlying their flame retardancy are reviewed. Besides classifying and interpreting the open literature on flame‐retardant hydrogels and aerogels, challenging aspects of future developments ahead of these advanced materials are highlighted.Highlights Briefly overviewed general features of hydrogels including synthesis and applications. Briefly overviewed principles of flame retardancy and flame‐retardant polymers. Reviewed and classified flame‐retardant hydrogels and aerogels as advanced materials. Summarized the latest advancements in flame‐retardant hydrogels and aerogels. Highlighted future fire protection by flame‐retardant hydrogels and aerogels.

“…Recently, forest fire is a global challenge that has been widely focused by many fire‐prone countries such as USA, Canada, China, Australia, and Russia. According to the previous reports, 1–4 the occurrence of forest fire as well as the combustion products often have destructive influences on the forest ecological environment and cause seriously threats to the animals and human lives 5–7 . Because forest wood is one of the most typical solid fuels, 8,9 it is more necessary to develop an effective wood coating to combat forest fire.…”

Herein, various of aqueous halogen‐free flame retardants (FRs) were fabricated by controlling the weight ratio of phosphorus/nitrogen/carbon compounds. The prepared FRs showed good dispersion level at ambient conditions and easily adhering feature on the wood substrate. Owing to the synergistic flame‐retardant effect of phosphorus/nitrogen/carbon compounds on wood, the FR1 coated wood (W‐FR1) could form non‐pores, compact, and continuous phospho‐carbonaceous layer under fire. Meanwhile, W‐FR1 exhibited a higher LOI (59.5%) and UL‐94 rating (V‐0). Moreover, the ignition time of W‐FR1 was significantly delayed from 35 to 570 s. Additionally, W‐FR1 showed 31.6% and 47.1% reductions in THR and TSP, respectively, 99.3% increment in char residue, as compared to the untreated wood. The present research offers a promising aqueous flame retardant for potential forest fire prevention.
