Aggregation behavior and interface properties of mixed surfactant systems gemini 14-s-14/CTABr

- Micelle structure of mixed systems gemini 14-s-14/CTABr were experimentally studied.
- Negative deviation from ideal behavior is found for mixed micelles 14-2-14/CTABr.
- Surface potential decreases if molar fraction of gemini surfactant in mixture ≥0.3.
- Degree of counterion binding follows the series 14-6-14 > 14-4-14 > 14-2-14.
