Abstract: According to the type of ionic liquid surfactants,the effect of the surfactant structure on the surface activity parameters,such as critical micelle concentration (cmc),lowest surface tension (γcmc),surface adsorption efficiency (pc20),maximun surface adsorption (Γmax) and minimum molecular sectional area (Amin) were summarized separately.As compared with traditional surfactants,the introduction of ionic liquid group upgrades surface active performance of the surfactant and varieties of surfactant were increased.The effect of alkyl carbon chain length on the surface active performance of ionic liquid surfactants is similar to that of the traditional surfactants.

Key words: surfactant, ionic liquid, surface tension, critical micelle concentration
