Green and Facile Synthesis of Bio-Based, Flame-Retardant, Latent Imidazole Curing Agent for Single-Component Epoxy Resin

“…Generally, introducing halogen-containing flame retardants is a common and efficient approach to address the flammability issue of polymeric materials. − Nonetheless, the application of halogen-containing flame retardants follows with a series of environmental and human-health issues. , Therefore, halogen-free flame retardants have drawn wide attention from both academic and industrial circles. In particular, phosphorus-containing flame retardants can simultaneously quench the high-energy fuel and promote the carbonization of the matrixes during combustion. − Hence, numerous phosphorus-containing flame retardants have been synthesized and introduced into EPs, e.g., phosphaphenanthrene, − ammonium polyphosphate, − organophosphate, − and cyclotriphosphazene. − Unlike the above petrochemical products, phytic acid (PA) originates from oil-bearing crops, which features a high phosphorus content of 28 wt %; thus, it has been recognized as one class of promising bio-based platform compounds. − To reduce the overexploitation of fossil resource and meet the sustainable development, many bio-based flame retardants derived from phytic acid have been developed. , For instance, Ye et al synthesized a phytic acid salt (PF) and applied it to flame-retardant poly­(lactic acid) (PLA). The resultant PLA exhibited enhanced flame retardancy, with a high LOI of 28.5% and a UL-94 V-0 rating.…”

Column-to-Beam Architecture Inspires Interface-Engineered MXene Nanosheet/Boron Nitride Nanosheet/Polydopamine Hybrids for Fire Retardants

“…Cone calorimeter tests (CCTs) have been widely used to assess the fire hazard of materials as an effective test method for simulating real combustion. − For the sake of evaluating the effect of nanohybrids on the flame-retardant performance of EP composites, the fire safety behavior of EP composites was studied using CCT and relevant data were obtained. The test result curves are exhibited in Figure a–i, while the important parameters are shown in Table , including PHRR, total heat release rate (THR), PSPR, and total smoke production (TSP).…”

Recent advances in fire‐retardant carbon‐based polymeric nanocomposites through fighting free radicals

“…In comparison, the condensed‐phase free radical scavengers reduce the smoke release during combustion and improve the thermo‐oxidative stability of polymeric nanocomposites more significantly. However, to achieve a satisfactory fire‐resistant effect in a polymer, they need to be combined with traditional flame retardants or chemically modified with flame‐retardant elements 150–153 . By contrast, the dual‐phase free‐radical scavengers have demonstrated desired fire‐retardant, smoke‐suppressant, and anti‐oxidation properties of polymers.…”
