“…The flame retardant effect is poor, and the compatibility of the material is poor. Therefore, most scholars focus on reducing the thermal conductivity of nitrogen flame retardants and improving material compatibility through modification [ 71 , 72 , 73 , 74 , 75 ].…”

Against the background of people’s increasing awareness of personal safety and property safety, the flame retardancy (FR) of materials has increasingly become the focus of attention in the field of construction engineering. A variety of materials have been developed in research and production in this field. Polymers have many advantages, such as their light weight, low water absorption, high flexibility, good chemical corrosion resistance, high specific strength, high specific modulus and low thermal conductivity, and are often applied to the field of construction engineering. However, the FR of unmodified polymer is not ideal, and new methods to make it more flame retardant are needed to enhance the FR. This article primarily introduces the flame-retardant mechanism of fire retardancy. It summarizes the preparation of polymer flame-retardant materials by adding different flame-retardant agents, and the application and research progress related to polymer flame-retardant materials in construction engineering.

“…Among these, phosphorus-based compounds are more effective and compatible with thermoplastics resins and thermoplastic polymers. In some specific flame retardants, promotional effects occur when combinations of P-N, P-Si, and N-Si compounds are used [ 112 , 115 , 116 , 117 , 118 , 119 ]. In many cases, the use of reactive co-monomers is preferred since epoxy resins flame-retarded with conventional additives have poorer physical properties than unmodified ones [ 120 , 121 , 122 , 123 , 124 , 125 ].…”

Currently, polymers are competing with metals and ceramics to realize various material characteristics, including mechanical and electrical properties. However, most polymers consist of organic matter, making them vulnerable to flames and high-temperature conditions. In addition, the combustion of polymers consisting of different types of organic matter results in various gaseous hazards. Therefore, to minimize the fire damage, there has been a significant demand for developing polymers that are fire resistant or flame retardant. From this viewpoint, it is crucial to design and synthesize thermally stable polymers that are less likely to decompose into combustible gaseous species under high-temperature conditions. Flame retardants can also be introduced to further reinforce the fire performance of polymers. In this review, the combustion process of organic matter, types of flame retardants, and common flammability testing methods are reviewed. Furthermore, the latest research trends in the use of versatile nanofillers to enhance the fire performance of polymeric materials are discussed with an emphasis on their underlying action, advantages, and disadvantages.

“…Thus, untreated AF is usually incompatible with polymeric materials. 24 The para-aramid nanofibers (ANF) can be obtained by deprotonating AF, which inherit its advantages of high temperature and corrosion resistance and overcome the disadvantage of complex modification. 25 Unfortunately, the compatibility of untreated ANF with TPU is still unchanged.…”

In this work, para‐aramid fibers were dispersed into para‐aramid nanofibers (ANF) by deprotonation process, and then modified by 3‐chloropropyne (PC) via covalent bonding interaction. The resultant nanofiber (ANF‐PC) as a flame retardant was blended with thermoplastic polyurethane (TPU) to obtain fire‐retardant TPU nanocomposites. The addition of 0.250 wt% ANF‐PC reduced the peak heat release rate, total heat release, total smoke release, and peak CO release rate of TPU by 47.7%, 31.5%, 16.4%, and 45.1%, respectively. The char yield of TPU/ANF‐PC0.250 was increased from 7.7% (TPU/ANF0.250) to 13.7%. The flame‐retardant effect of ANF‐PC in TPU composites can be attributed to its carbonization effect in the condensed phase, which increased the char yields and graphitization degree of char residue. In addition, the presence of ANF‐PC increased the tensile strength and breaking strain of TPU by 645% and 578% compared to untreated ANF, due to the improved dispersion state of ANF‐PC.
