Claim:
1. A method for coating a substrate to provide a flame resistant substrate, comprising: (A) depositing a primer layer onto the substrate, wherein the primer layer comprises a surface, and wherein the surface of the primer layer proximate to the substrate is neutral or is charged with an attraction to the substrate; (B) exposing the substrate to a cationic solution to produce a cationic layer deposited on the substrate, wherein the cationic solution comprises a cationic material, and wherein the cationic material comprises a polymer, a colloidal particle, a nanoparticle, a nitrogen-rich molecule, or any combinations thereof, wherein the cationic material does not comprise a clay, and wherein the substrate comprises foam, fabric, or any combinations thereof; (C) exposing the cationic layer to an anionic solution to produce an anionic layer deposited on the cationic layer to produce the flame resistant substrate having a layer comprising the anionic layer and the cationic layer, wherein the anionic solution comprises a layerable material, and wherein the layerable material does not comprise a clay; and further wherein the primer layer comprises a primer layer material which is different from any cationic material in any cationic layer and any layerable material in any anionic layer.
