In this work, we synthesized novel poly (ethylene oxide)-b-poly (ε-caprolactone)-b-poly (ethylene oxide) triblock copolymers by condensation reaction with different the hydrophilic lipophilic balance. Through their micellization and emulsification behaviors, we figured out that their assembly at the oil-water interface enabled the production of highly stable nanoemulsions by the formation of a resilient thin polymeric membrane at the interface. From dense suspension rheological studies, we figured out that the nanoemulsions produced using the triblock polymeric surfactants showed typical linear viscoelastic behavior in a wide range of temperature, thus revealing their excellent endurance against high external stresses. We expect that the polymeric surfactants synthesized in our study would replace the typical low molecular weight surfactants for development of a variety of complex formulations. |
