Novel P/N/Si/S-containing Mononickel Complex as a Metal-based Intumescent Flame Retardant for Cotton Fabrics

Recent developments in phosphorus based flame retardant coatings for textiles: Synthesis, applications and performance

“…Cotton fabric was treated with an intumescent FR system possessing organic heteroatoms as ligand coordinated to nickel [164]. Initially, P, N, Si and S based ligand was complexed with NiCl 2 through the coordination of lone pairs of phosphorus to form 117 with a yield of 93 % (Scheme 60).…”

An Organometallic Flame Retardant Containing P/N/S–Cu2+ for Epoxy Resins with Reduced Fire Hazard and Smoke Toxicity

“…Though these phosphorus and nitrogen organic flame retardants can effectively enhance the flame-retardant performance of EP, they have less effect on the release of smoke during the burning of EP. Metal oxides and their hydroxides can be used as inorganic flame retardants to effectively improve the smoke suppression performance of polymeric materials, − but owing to their low flame-retardant efficiency, it has to be added in large quantities to obtain the fireproof effect, which seriously damages the mechanical properties of polymeric materials . Much research has been conducted to show that the combination of metal ions introduced into flame retardants can successfully reduce the smoke emissions from the burning of compound materials − and catalyze the conversion of toxic gases, significantly reducing environmental pollution.…”

Durable flame‐retardant cotton fabric modified by water‐soluble C–N–P intumescent flame retardant

“…It demonstrates the potential of IFR to improve the flame retardancy of cotton‐containing fabrics by improving water solubility 15 . The single nickel complex incorporating P/N/Si/S is utilized as a metal‐based IFR for cotton fabric, with NiS catalyzing the creation of a dense carbon layer and the release of flammable gas 16 . Poly(dimethoxy)phosphazene (PDMP), as an integrated IFR for cotton fabrics, exhibits enhanced carbonization ability at the low temperature, and maintains self‐extinguishing performance and high LOI values (28.6) after 50 washing cycles 17 .…”
