High strength, low flammability, and smoke suppression for epoxy thermoset enabled by a low-loading phosphorus-nitrogen-silicon compound

Wenhui Rao et al.

Summary: The novel phosphorus/nitrogen-containing phenylsiloxane macromolecule (DP-PPD) serves as a multi-functional additive to enhance the mechanical strength, flame retardancy, and smoke suppression performance of EP resin. With a low loading of DP-PPD, significant improvements in impact strength, flexural strength, and flexural modulus of EP were achieved. Combining aromatic rings, siloxane, and DOPO units, DP-PPD synergistically promotes the formation of a P-Si-containing hybrid char layer for EP resins during combustion, leading to satisfactory flame retardancy and smoke suppression.

MXene based core-shell flame retardant towards reducing fire hazards of thermoplastic polyurethane

Chuan Liu et al.

Summary: This study introduced a novel method to enhance the fire safety of TPU composites by functionalizing APP with Ti3C2Tx and CS, resulting in improved thermal stability and reduced heat and smoke release. The synergistic effect between APP@CS and Ti3C2Tx, combined with the trapping effect of APP@CS, significantly enhanced the fire resistance of the polymeric material.

A molecularly engineered bioderived polyphosphate for enhanced flame retardant, UV-blocking and mechanical properties of poly(lactic acid)

Yan Zhang et al.

Summary: This study reports the synthesis of a novel multifunctional bioderived polyphosphate (PPD) using plant-derived diphenolic acid for PLA, which enables PLA to achieve desirable flame retardancy and high UV protection. Adding 6wt% of PPD results in a 31% increase in impact toughness and a slight improvement in tensile strength for PLA.

Eco-friendly flame retardant and dripping-resistant of polyester/cotton blend fabrics through layer-by-layer assembly fully bio-based chitosan/phytic acid coating

Yinchun Fang et al.

Summary: Polyester/cotton blend fabrics combine the comfort of cotton and the mechanical strength of polyester, but their high flammability poses potential fire hazards due to the wick effect. A bio-based intumescent flame retardant coating of chitosan/phytic acid was successfully applied to improve flame retardancy and eliminate dripping of the fabric. This research offers a new eco-friendly flame retardant strategy for polyester/cotton blend fabrics using a bio-based IFR system.

Eco-friendly phosphonic acid piperazine salt toward high-efficiency smoke suppression and flame retardancy for epoxy resins

Yue Xu et al.

Summary: In this study, a novel eco-friendly flame-retardant phosphonic acid piperazine salt was successfully synthesized and used to enhance the flame-retardant and smoke-suppression properties of epoxy resins. The introduction of PTPAP promoted the charring of EP matrix, reduced smoke and heat emission, and improved fire safety. The flame-retardant EP/PTPAP thermosets showed great potential for applications in sustainable development due to the simplicity and environmental friendliness of PTPAP synthesis.
