摘　　要：简要介绍了近期开发Gemini稳泡剂的一些结果。实验发现,Gemini两亲结构非常适合于构筑分子致密排列的吸附膜,因此能够作为高效稳泡剂使用。其中连接基修饰上羟基的Gemini表面活性剂可以发挥分子间氢键的促致密作用,增长烷烃尾链长度有助于增强分子间氢键相互作用。但是与这些作用相比,直接利用短连接基能够产生更本质意义上的改善,从而获得高稳定性的泡沫体系。The recent development of high efficient foam stabilizer based on gemini surfactants was introduced briefly in this paper. The gemini-structure of amphiphile was found to be very suitable to the construction of the adsorption film with tightly packing of molecules and therefore to be possible as a high efficient foam stabilizer. The hydroxyl-substituted spacers of geminis could play the role of promoting molecules packing tightly. This role could be further enhanced by increasing the length of alkyl tails. Compared with this role, however, the improvement of the adsorption film structure might be more evident directly using the gemini surfactant with a short spacer, by which a highly stable foam system could be produced.
