Abstract: A cured product of a liquid complex coacervate includes a macroion phase of a polyanion, a polycation, and a salt; wherein the polyanion has repeating units including one or more of a carboxylate group, a sulfonate group, a phosphonate group, a sulfate group, or a phosphate group; and wherein the polycation has repeating units including one or more of a nitrogen-containing cationic group, a phosphorus-containing cationic group, or a sulfur-containing cationic group; provided that when the polycation is poly(diallyldimethyl ammonium), the poly anion is not polystyrene sulfonate, or when the polyanion is polystyrene sulfonate, the polycation is not poly(diallyldimethyl ammonium). Methods of forming coatings are also disclosed.
