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.
