Although interfacial modification by microwave selective heating has been reported in previous study, it was difficult to estimate the thermal energy concentration of the absorption at liquid-liquid interface. In this study, optimum operation of microwave pulse mode was investigated to enhance the effect of surfactant desorption by using our dimensionless number of the local heating. According to the results, it was found that power is an important factor for the quick thermal response of interfacial tension. Finally, dimensionless number is expected to be a good tool for controlling heat transfer at the interface.
