In this work, we synthesized poly (ethylene oxide)-b-poly (ε-caprolactone)-b-poly (ethylene oxide) triblock copolymers with varying the hydrophilic lipophilic balance (HLB) by using condensation reaction. We showed 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 the typical linear viscoelastic behavior in a wide temperature range, thus exhibiting the excellent endurance against high external stresses. We expect that the polymeric surfactants synthesized in our study would provide opportunities to development of a variety of complex emulsion formulations. |
