Introduction

Among the unique properties of ionic liquids, surface tension plays a special and crucial role. Since the ionic nature of ILs makes it extremely difficult to accurately measure the cohesive forces present in the liquid, in view of this situation, the corresponding states principles and other powerful correlation techniques are often applied to solve the issue, which is also still a challenge. So it is found that surface tension value is an effective way to avoid this problem, and it is possible to access at the liquid-vacuum boundary. Surface tension is a measure of cohesive forces between liquid molecules present at the surface, and it represents the quantification of force per unit length of free energy per unit area. Thus, the measurement of surface tension of ionic liquids is one of the most effective ways to (indirectly) access the intrinsic energetics that are involved in the interactions between the ions [1]. In addition, surface tension data are also a powerful...
