WitrynaThis primary emulsion is used as the basic layer for the oppositely charged polyelectrolyte which is added to the system and adsorbed onto the droplet surfaces. Thus, the secondary emulsion structure containing oil droplets coated with a two-layer interface is produced. WitrynaThis method is suitable for both natural and synthetic polymers. In this technique, polymers are dissolved in an organic solvent and emulsified into an aqueous phase to form a water-in-oil emulsion. As a result, two emulsions are made. The primary emulsion is subjected to homogenization and dropped into an aqueous solution.
