Abstract: A flame retardant composition comprising chitosan or a modified chitosan, as well as a method for preparing a flame retardant comprising chitosan or a modified chitosan, is provided. Also provided are methods for making a flame retardant article using the described flame retardant composition. In various embodiments, the flame retardant composition is prepared by dissolution of chitosan or a modified chitosan by an aqueous acid, followed by evaporation of the water. In various embodiments, the flame retardant composition can further include at least one additional component selected from the group consisting of a polyol, flame retardant, nitrogen containing compound, carbonate containing compound, crosslinking agent, and combinations thereof.

Abstract: A flame retardant coating composition comprising poly(dopamine) and either tris(hydroxymethyl)aminomethane) or gaseous ammonia, as well as an article comprising a substrate and the flame retardant coating composition, is provided. In various embodiments, the poly(dopamine) is substantially water insoluble. The coating composition can further comprise at least one additional component selected from the group consisting of melamine, an anionic clay, a phosphorus-containing compound, an amine-containing compound, aluminosilicates, silicon oxides, and combinations thereof. Also provided are methods for forming the flame retardant coating composition and methods for increasing flame retardant properties of a substrate.
