Claim:
1. A method for coating a substrate to provide a flame resistant substrate, comprising: (A) exposing the substrate to a cationic solution to produce a cationic layer deposited on the substrate, wherein the cationic solution comprises cationic materials, and wherein the cationic materials comprise polyethylene oxide, polyallylamine, or any combinations thereof, and wherein the cationic materials do not comprise a clay; (B) 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 bilayer 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; wherein the substrate is a foam or fabric.
