离子液体表面活性剂的合成与应用(Ⅳ)——离子液体表面活性剂的表面活性

Synthesis and application of ionic liquid surfactants(Ⅳ) Surface activities

按照离子液体表面活性剂的分类,分别综述了表面活性剂分子结构对临界胶束浓度(cmc)、最低表面张力(γ_(cmc))、表面吸附效率(pc_(20))、表面饱和吸附量(Γ_(max))和分子最小截面积(A_(min))等表面活性参数的影响。与传统表面活性剂相比,离子液体结构的引入提高了表面活性剂的表面活性,丰富了表面活性剂的品种。烷基碳链长度对表面活性的影响与传统表面活性剂相似。

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 （？cmc）, surface adsorption efficiency （pc20）, maximun surface adsorption （Gmax） 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.
