Gemini表面活性剂在固液界面的吸附及增溶作用

Adsorption and Adsomubilization of Gemini Surfactants at Solid/Liquid Interface

介绍了一类新型表面活性剂———Gemini表面活性剂。这类表面活性剂具有特殊的分(离)子结构,其分(离)子由两(或三)条疏水链、两个亲水基和一个连接基组成。综述了Gemini表面活性剂在固液界面的吸附及增溶作用,其在固液界面的吸附及增溶作用与固体表面的性质及其分(离)子结构有很大关系。

A new kind of surfactant（Gemini surfactant） is introduced. It has especial molecular（ionic）structure. The molecule（ion）is made up of two （or three） hydrophobic chains and two hydrophilic heads connected by a spacer group. The adsorption and adsolubilization of Gemini surfactant on solid/liquid interface are reviewed. Its adsorption and adsolubilization on solid/liquid interface are closely related to the properties of the solid surface and its molecular（ionic） structure.
