1. A method of applying a gas-impermeable coating, the method comprising:
forming a polyelectrolyte complex suspension;
applying the polyelectrolyte complex suspension to a substrate, the polyelectrolyte complex suspension comprising a molar ratio of 1:3 of polycation to polyanion;
treating the substrate having the polyelectrolyte complex applied thereon, wherein the treating reduces salt content of the polyelectrolyte complex and causes solid film formation on the substrate; and
wherein, the treating results in a gas-impermeable coating being formed on the substrate.
