通过平衡表面张力的测定,研究了聚氧乙烯山梨醇酐脂肪酸酯(Tween)系列与聚氧乙烯(10)油基醚(Brij97)混合胶束形成的相互作用参数βm、分子交换能εm及热力学参数(△Gom、△Hom、△Som),并探讨了Tween系列分子结构、混合体系的组成及温度对胶束形成的影响.研究表明,随着Tween碳链的增大,混合胶束中Tween的摩尔分数XM1增大,协同效应增强;在Tween60/Brij97混合胶束中,△Gom随着Tween60摩尔分数(α1)的增大而增大;在混合胶束形成中,α1≤0.33时,两组分表现出协同效应;在α1＞0.33时,未表现出协同效应;温度对Tween60/Brij97混合体系的影响表明,温度升高,CMC和△Gom小,△Hom和△Som增大,协同效应减弱.
