The Additives Effect on the Nanostructures and Microstructures Properties in Gemini Surfactants Aqueous Solution

Gemini – type surfactants are surfactants that have two hydrophilic and two hydrophobic groups in the molecule, rather than the one hydrophobic and hydrophilic group of conventional surfactant. They have much lower critical micelle concentration (cmc), better lime-soap dispersing, and better wetting properties. [1-4] In present work, the adsorption behavior at the liquid-air interface and aggregation characteristics were investigated in Gemini surfactants in aqueous media containing different concentrations of salt and alcohol by surface tension and conductometry measurements. Also, the effects of these additives were studied on the size and transition from nanostructures to microstructures and vice versa
