Summary: A novel flame retardant containing high amounts of P and N elements was designed and grafted onto cotton fabric via P-O-C covalent bonds, showing improved flame retardancy and durability. The treated cotton exhibited lower peak heat release rate, total heat release, and initial decomposition temperatures, as well as increased carbon residue during combustion, indicating the formation of an expanded char layer. Various spectroscopic techniques confirmed the flame retardant mechanism, and the mechanical properties of the treated cotton remained suitable for use after treatment.

Summary: In recent years, indoor fires caused by the flammable properties of cotton have become increasingly common, emphasizing the importance of flame-retardant cotton. Researchers have successfully developed a new flame retardant that forms stable chemical and coordination bonds on the surface of cotton fibers through a simple finishing process. This flame retardant exhibits excellent durable flame retardancy and does not significantly affect the physical properties of cotton fabric.

Summary: In this study, a reactive flame retardant for epoxy resin was prepared using tryptamine, 9,10-dihydro-9-oxa10-phospha-phenanthrene-10-oxide, and vanillin as reaction monomers. The addition of a small amount of flame retardant improved the thermal stability and flame resistance of the epoxy resin, and the flame-retardancy mechanism was studied using thermogravimetric analysis/infrared spectroscopy and scanning electron microscopy.

Summary: There is a high demand for nontoxic flame retardants in the textile industry to replace harmful alternatives. However, eco-friendly phosphorus-based flame retardants for synthetic textiles are scarce, especially for back coating application. In this study, non-toxic phosphorus flame retardants (such as EDA-DOPO and DOPO-PEPA) were applied to PET fabric via a back coating process using different polymer resins. The fabrics' flame retardant performance was evaluated using the vertical burning test, and it was found that DOPO-based FR compounds were effective, but the addition of melamine was necessary to improve the performance of DOPO-PEPA formulations.

Summary: DOPO-ETES and DOPO-AmdPTES were synthesized as halogen-free flame retardants without by-products. They were applied on cotton fabric using sol-gel method and pad-dry-cure finishing process. DOPO-AmdPTES-treated cotton exhibited self-extinguishing behavior with high char residue, improved LOI value and reduced PHRR, HRC and THR compared to untreated cotton. DOPO-AmdPTES-treated cotton showed semi-durability after ten laundering cycles. According to the results, the flame retardant activity occurred in the condensed phase as a physical barrier and in the gas phase through dilution effect.

Summary: The synthesis of tetra-DOPO compound enhanced the flame-retardant efficacy of epoxy thermosets without compromising their thermo-mechanical performances. The addition of 5.0 wt% of tetra-DOPO improved storage modulus, glass transition temperature, LOI, and UL-94 V-0 grade of the EP composite, demonstrating exceptional fire-retardant properties. The flame inhibition mechanism of tetra-DOPO was further elucidated through various tests, clarifying its role in both vapor and condensed phases.
