Summary: Recent research in the construction field focuses on developing biomass flame-retardants and thermally-insulating materials. By exploiting the synergistic effect of additives, flame-retardant tannin-furanic-SPI bio-foams with outstanding thermal insulation and smoke suppression performance were developed. These foams exhibit closed cell structures, good thermal stability, low thermal conductivity, and have potential applications as thermal insulation for buildings.

Summary: The study focuses on the synthesis of new Co(II) and Ni(II) metal complexes as flame retardant additives in paint formulations. The results show that the prepared metal complexes significantly improved the flame retardancy of the paint without affecting the physical and mechanical characteristics of the coatings. The incorporation of the aromatic ring and oil level in the formulation also improved the gloss of the paint film.

Summary: The improvement of electrical insulation performance of pure PDMS materials during a wildfire event was explored in this study. The results showed that SR composites prepared with MGFs and GNPs can further enhance the properties of pure ATH-filled PDMS. SR4 and SR5 exhibited significantly improved LOI and maintained a high level of static contact angle, demonstrating good fire retardancy, mechanical strength, and hydrophobicity.

Summary: The synergistic effect of the silane coupling agent (KH550) and carboxymethyl chitosan (CMCS) co-modified boron nitride (BN) on the fireproof property of silicone acrylic emulsion-based composite was investigated. The results showed that an appropriate loading of BN enhanced flame retardancy and improved the water resistance of the coating. The co-modified BN reacted with phosphoric acid and increased the thermal insulation of the coating.

Summary: This study demonstrates the fabrication of cellulose nanocrystal (CNC) aerogels with balanced thermal and mechanical performance through a 1 nm metal oxide cluster-assisted freeze-drying process. The hybrid aerogels exhibit hierarchical porous structures composed of layer-by-layer CNC nanosheets, enabling the independent enhancement of mechanical properties and thermal insulation capabilities. The addition of phosphotungstic acid clusters contributes to the formation of continuous networks and improved fire-retardant properties.

Summary: A high-efficiency durable flame retardant (THPO-P) was synthesized and chemically bonded to cotton fabric, significantly improving its flame retardancy and durability. The treated fabric exhibited excellent fire safety and durability, with significant reductions in total heat release and peak heat release rate values. The flame-retardant treatment process did degrade some physical properties of the cotton fabric.

Summary: In this study, novel soybean oil-based waterborne polyurethane coatings and films with significantly improved fracture toughness and flame retardancy were successfully synthesized using chain extenders BH and BDO. The mechanical properties of SPU films were effectively improved by the introduction of BH, showing remarkable enhancements in tensile strength, elongation at break, and fracture toughness. The flame retardancy of SPU films increased gradually with the BH molar content, reaching a high LOI value of 28.2% for SPU80 with 0.9 wt% phosphorus content.

Summary: Nano calcium carbonate was treated with tetrabutyl titanate sol and nickel hydroxide, resulting in the formation of a new flame retardant called Ni-TiO2@CaCO3. This flame retardant was then introduced into epoxy resin to improve its flame retardancy and thermal stability. The addition of Ni-TiO2@CaCO3 significantly reduced the peak heat release rate and smoke production rate of the epoxy resin, and improved its degradation temperature and char residues. The flame retardancy mechanism of the Ni-TiO2@CaCO3/EP composite was thoroughly analyzed using various methods.

Summary: A novel methionine-based flame retardant with P, N, and S elements was synthesized for cotton fabrics, showing excellent flame retardancy and durability. The flame retardant changed cellulose decomposition pathway, reducing combustible gases and increasing residue. The treated fibers had decreased total heat release and slightly lower tensile strength, but no free formaldehyde content was detected, highlighting its effectiveness as a biologically-based and durable flame retardant.
