Abstract: A textile includes a substrate and a coating applied to a surface of the substrate. The coating includes a plurality of bilayers positioned one on top of the other. Each bilayer includes a first layer including a cationic polymer and a second layer comprising an anionic polymer. The cationic polymer in the first layer includes a polyethyleneimine (PEI), a poly(vinyl amine) (PVAm), a poly(allyl amine) (PAAm), a polydiallyldimethylammonium chloride (PDDA), or a chitosan (CH). The anionic polymer in the second layer includes a poly(acrylic acid) (PAA), a poly(styrene sulfonate) (PSS), a poly(methacrylic acid) (PMAA), a poly(sodium phosphate) (PSP), or a poly(vinyl sulfate) (PVS).

Abstract: A coating for protecting a metal substrate from corrosion comprising a first composition applied on or over the metal substrate and a second composition applied on or over the first composition. The first composition is positioned between the second composition and the metal substrate, the first composition includes a first layer directly applied on or over the metal substrate and a second layer directly applied on or over the first layer, and the first layer of the first composition is positioned between the second layer of the first composition and the metal substrate. The first layer of the first composition comprises positively charged polymers and the second layer comprises negatively charged polymers and the second composition comprises positively charged polymers and negatively charged silicate clay.
