“…Hexagonal boron nitride (h-BN) is a graphene-like compound with an isoelectronic structure. 27,28 The high thermal conductivity 29 (200-600 W/Mk) and excellent thermal stability 30,31 are of great interest to experts and scholars. These excellent properties make it possible to prepare new PBS flame-retardants 32 with other flameretardants.…”

This article describes the preparation of nitrogen‐phosphorus‐doped boron nitride (BN@APP) as a multifunctional nanofiller for flame‐retardant and thermal conductivity in polybutylene succinate (PBS). The BN@APP was obtained by a one‐step ball milling method. The improvement of thermal conductivity effectively reduces the generation of toxic smoke during PBS combustion. After incorporating 1.0 wt% BN@APP into the PBS, the thermal conductivity of the PBS composite is increased by 62.8%. The heat and toxic smoke are reduced significantly, the heat release rate, total heat release, and total smoke rate of PBS composites were dramatically reduced by 28.2%, 23.5%, and 44.8%, respectively, compared to pure PBS. This research offers a prospective route to prepare highly flame‐retardant composites that have low‐toxicity and smoke.

“…Meanwhile, the extremely high thermal stability promotes the application of BN nanosheets in some special fields . For example, the layered structure and thermal stability have made BN nanosheets the ideal nanofillers in flame-retardant polymer composites. , It is found that BN nanosheets effectively suppress the delivery of heat and mass between fire and a polymer by building a robust defense layer . However, it has been realized gradually that the fire hazards of polymer composites do not consist of merely heat but also include toxic smoke particles. , Due to the lack of metal elements and a large band gap, the toxic smoke suppression of BN nanosheets with a low catalysis effect leaves much to be desired …”

The heterolayered architecture design is capable of assembling different nanomaterials into a multifunctional nanohybrid. Herein, based on an electrostatic-driven self-assembly process, polyaniline-modified boron nitride (BN/PANI) nanosheets are fixated onto the surface of molybdenum disulfide (MoS2) nanosheets, thus forming a multifunctional heterolayered architecture nanohybrid. Based on the barrier effect of BN nanosheets and the Lewis acid catalysis effect and the chain rearrangement effect of MoS2, the prepared BN/PANI/MoS2 presents a desirable enhancement effect in the flame retardancy and toxic smoke suppression of epoxy resins. Meanwhile, in a high-temperature environment, the charge carrier produced by MoS2 nanosheets is rapidly transferred by electric BN/PANI, thus accelerating the formation of a protective char layer. It was found that 5.0 wt % addition of BN/PANI/MoS2, respectively, leads to decreases of 23.7, 9.1, 11.1, and 29.9% to the peak heat release rate, total heat release, peak smoke release rate, and total smoke release. In this work, in terms of the design of heterolayered architecture, the unique function of solo nanomaterial is effectively integrated to obtain the optimal effect, thus promoting the application of nanohybrids in polymer composites.

“…Different from the above two methods, coating is another effective flame‐retardant method 11 . This method is often used for flame‐retardant fabrics, 12,13 and some researchers have applied it to flame retardance of polyurethane foam 14 . Wang et al 15 studied synthetic silicone resin (poly‐DDPM) and expandable graphite (EG) mixed coating to RPUF that gave RPUF excellent flame‐retardant properties.…”

In this paper, a boron phenolic (BPR)/silica sol (Si-sol) coated flame retardant was prepared, and the flame retardant was coated on the surface of rigid polyurethane foam (RPUF) to make it have excellent flame-retardant effects. The molecular structure of BPR and Si-sol was analyzed by FTIR, and the influence of the coating on the cells was observed with an optical microscope. It was evident from the test results of the cone calorimeter that the peak heat release rate (PHRR) and total heat release (THR) of RPUF were reduced by 45% and 37.7%, respectively. The limit oxygen index and vertical combustion test results indicated that the LOI reached 35%, and UL-94 reached the V-0 level. The aging experiment was conducted on the coated RPUF material, and the results showed that the material has long-lasting flame-retardant properties. The possible flame-retardant mechanism was analyzed.
