A method of applying a gas-impermeable coating includes forming a polyelectrolyte complex suspension. The polyelectrolyte complex suspension is applied to a substrate. The substrate having the polyelectrolyte complex applied thereon is treated. The treating reduces salt content of the polyelectrolyte complex. The treating results in a gas-impermeable coating being formed on the substrate.

Method for applying gas-impermeable coatings

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).
