Exploration on structural rules of highly efficient flame retardant unsaturated polyester resins

Fukai Chu et al.

Summary: The lack of research on structure-activity relationship and interaction mechanism between unsaturated polyester resins (UPR) and flame retardants has posed challenges for developing high-efficiency flame retardants in industry. This study synthesized various polymeric flame retardants and evaluated their thermal stabilities, uncovering the interaction mechanisms and rules for improving flame retardancy of UPR composites. Key findings included the role of gaseous phase flame retardant mechanism and the effectiveness of phosphorus structures and sulfone groups in enhancing flame retardant efficiency.

The flame retardancy of ionic liquid functionalized graphene oxide in unsaturated polyester resins

Ming Gao et al.

Summary: The study shows that by modifying GO to ILGO and compounding it with traditional flame retardants, the flame retardancy of UPR materials can be improved, reducing the temperature and carbon residue during combustion. ILGO can promote the formation of more residual carbon in UPR, enhancing the material's thermal stability and reducing combustibility.

Innovative design of environmentally friendly silicon-based polyphosphazene-functionalized hydroxyapatite nanowires: An efficient enhancement strategy for the fire safety and mechanical properties of unsaturated polyester

Yifan Zhou et al.

Summary: In this study, an environmentally-friendly nanohybrid material, f-HAPNW, was prepared by modifying hydroxyapatite nanowires (HAPNW) with polyphosphazene crosslinked by hexachlorocyclotriphosphazene (HCCP), 3-aminopropyltriethoxysilane (APTES), and dopamine (DA). The incorporation of f-HAPNW into unsaturated polyester (UPR) matrix resulted in improved fire safety and mechanical properties of UPR nanocomposites. The introduction of bio-based materials and environmentally friendly flame retardants achieved significant flame-retardant filler efficiency while reducing smoke release and environmental pollution. This work provides a reference idea for the design of high-performance UPR nanocomposites.

MOF-derived strategy to obtain CuCoOx functionalized HO-BN: A novel design to enhance the toughness, fire safety and heat resistance of bismaleimide resin

Yifan Zhou et al.

Summary: In this study, a new type of nano-hybrid was obtained by generating copper-cobalt metal oxide on the surface of hydroxylated boron nitride using the MOF-derived strategy. The nano-hybrid was then dispersed in bismaleimide resin, leading to a strong interface interaction. The addition of the nano-hybrid effectively suppressed fire hazard and toxic smoke release, while also improving impact strength and glass transition temperature, expanding the potential application in extreme environments.
