Abstract
A method for nanoencapsulation of an amine adduct in a polymeric shell includes steps of emulsifying a first aqueous solution including the amine adduct into an organic solution including an organic solvent and a polymer to obtain a primary emulsion; emulsifying the primary emulsion into a second aqueous phase including a stabilizer to obtain a secondary emulsion; removing the organic solvent by evaporation to form solid nanocapsules; and separating the formed solid nanocapsules by centrifugation. The nanocapsules have an average size of between about 30 nm and about 597 nm
