Abstract: The values of cmc, Nagg and micelle micropolarity of the Gemini surfactants have been measured by fluorescence. The nature effect of the spacer on the aggregation properties of Gemini surfactants in the aqueous solution has been investigated. With the increae of spacer length, Nagg decreased, while the values of cmc, γcmc and the micelle micropolarity increased.

Key words: surfactant, Gemini, aggregation, spacer
