Abstract
A series of gemini surfactants 12-s-12 were successfully prepared and characterized,and their surface activities were evaluated by means of surface tension and electrical conductivity methods.The results showed that all products have better surface activities.However,the space groups have a great influence on the surface activites of these gemini surfactants—the shorter the space group,the better the surface activities.
