- •
ITC provided thermodynamic characterization of self-association of oppositely charged gemini/SDS surfactants.
- •
Phase transitions and corresponding enthalpies were obtained by ITC.
- •
The transitions reflect a change in morphology, supported by Cryo-TEM images.
- •
Conductivity and ITC results show very good agreement.
- •
An asymmetric distribution of surfactants in the aggregates is supported by results.
