    • The temperature-induced significant change in the interfacial tension could be related to the configurations of the P123 copolymer surfactant at the oil alkanes, water interface. At lower temperature, the PEO brushes and even the PPO blocks of the P123 copolymers surfactant should be stretched and spread separately at the oil/water interface, which results in a significant decrease in interfacial tension. As the temperature increases, as a result of the dehydration of PPO blocks and thus increasing hydrophobicity, more and more P123 copolymer surfactant would aggregate into large micelles with alkanes solubilized with their hydrophobic cores, which will lead to a sudden decrease in the number of P123 surfactant molecules at the oil/water interface and thus a sudden increase in interfacial tension
