Phosphorus and nitrogen functionalised silica showed to be an effective flame retardant in thermoplastic polyurethane. Silica was amine then propargyl functionalised, then reacted with a phosphorus and nitrogen containing derivate of pentaerythritol using alkine-azyde...
P-functionalised polyethyleneimine with iron salt achieved UL 94 V-0 in epoxy and improved mechanical properties. The commercial nitrogen containing polymer polyethylenimine (PEI) was reacted with phosphoric acid, then combined with ferric (Fe3+) salt, giving an iron...
Phytic acid (natural organophosphate), with melamine and metal ions, reduced fire, smoke and toxic gases in polyamide. Melamine (an organo-nitrogen molecule) was reacted with phytic acid (the biological phosphorus storage molecule of plants) to produce melamine...
PIN mineral salts and water-borne epoxy were used to fire safety treat wood, reducing flammability and fire gas toxicity. Fire safety is critical to enable use of wood as a renewable carbon-sink material for green building. PIN mineral salts, with good environment...
