Emulsions typically consist of dispersed droplets in a continuous phase, and they naturally tend to separate due to interfacial energy, leading to droplet coalescence. 

Copolymers are designed for stabilizing emulsions or droplets, which are mixtures of two immiscible fluid phases. The invention uses random amphiphilic copolymers that can stabilize these emulsions by reducing interfacial energy and thus increasing emulsion lifetime. These copolymers possess both hydrophobic and hydrophilic parts, allowing them to interact with both phases of the emulsion and form a kinetic barrier to droplet coalescence.

The invention also introduces methods for creating, using, and making compositions that include these copolymers. These compositions can encapsulate aqueous droplets within a polymeric film in an immiscible fluid, or vice versa, with oil droplets encapsulated in aqueous fluid. The polymer films are formed through the interaction of the copolymers with a hydrophilic complexing molecule, enhancing the stability and functionality of the emulsions or droplets for various applications. This approach opens up new possibilities for the use of emulsions in different products and industries by providing a means to control and maintain the stability of emulsions under various conditions.
