- (b) m is an integer 1 to 6,
- (c) Z is —OH or NR3R4, where R3 and R4 are each independently H or C1 to C6 straight-chain or branched alkyl group, and,
- (d) A− is an anion selected from the group consisting of [BF4]−,[PF6]−, [CH3CO2]−, [HSO4]−, [CF3SO3]−, [(CF3SO2)2N]−, [(CF3SO2)3C]−, [SO4]2−, Cl31, Br−, I−, [N(CN)2]−, [(PO4)(C4H9)2]−, [(PO4)(C2H5)2]−, [(PO4) (C6H5)2]−, [CH3CH2OSO3]−, [CH3OCO2]− and amino acid, and wherein the ionic liquid has flame retardant property.
A flame retardant fabric product comprising a fabric, a flame retardant ionic liquid represented by Formula 3, and a binder.
- wherein about 1% to about 60% by weight of the flame retardant fabric product comprises the flame retardant ionic liquid,
- wherein the fabric is selected from the group consisting of Cotton, Cellulose, Rayon, Nylon, Polyester, Polyurethane Polyamide, and Aramid.
