Thermodynamic properties of new gluconamide-based cationic surfactants in aqueous solution: Experimental and modeling approaches

The micellization processes of 2-(alkyldimethylammonio)ethylgluconamide bromides (CnGAB), dodecyltrimethylammonium bromide (DTAB) and dodecylethyldimethylammonium bromide (DEDAB) were studied using solution conductivity and isothermal titration calorimetry (ITC). The critical micelle concentrations (CMC), the degree of counterion binding (β), the enthalpies (ΔHm) and entropies (ΔSm) of micellization as well as the contributions of the headgroups...
