Tween80/AEO20体系胶束形成的分子间相互作用
Molecule Interaction in Mixed Micelle Formed by Oleyl Polyoxyethylene（20） and Tween80 System
摘要
Abstract
The surface tension of oleyl polyoxyethylene（20）（AEO20）with Tween80 was determined by a Wilhelmy type surface tension-meter.The influence of temperature on equilibrium surface tension was studied.The interactions between the two surfactant molecules in mixed micelle were studied through CMC,γCMC,pC20,Γmax,Amin.Moreover Clint＇s and Rubingh＇s treatments were used to analyze the molecular interaction parameters（βm） and the molecule exchange energy（εm）.For systems investigated,it showed that surface activity was advanced.There was a stronger synergistic mixing behaviour between AEO20 and Tween80 in some conditions.At 25℃ all mixtures showed synergism most evidently.At 30℃ and 35℃,when αAEO20 0.50 mixtures showed negative deviation,while βm and εm values of the mixed micelles ranged-1.84 and-12.47,-0.51 kJ/mol and-5.32 kJ/mol for all mixtures investigated.关键词
