    摘要: A coated substrate and method for producing the coated substrate provide a material diffusion barrier. In an embodiment, a method for producing a material diffusion barrier comprising a coating on an elastomeric substrate includes exposing the elastomeric substrate to a cationic solution to produce a cationic layer on the elastomeric substrate. The cationic solution comprises a polymer, a colloidal particle, a nanoparticle, a salt, or any combinations thereof. The method further includes exposing the cationic layer to an anionic solution to produce an anionic layer on the cationic layer. The anionic solution comprises an anionic polymer, a second colloidal particle, a second salt, or any combinations thereof. The coating comprises a bilayer comprising the cationic layer and the anionic layer.
