| Résumé : |
Two novel imidazoline gemini surfactants quaternary ammonium salts of di(2-undecyl (heptadecyl)-1-formyl aminoethyl imidazoline) hexanediamine (SUAEIHDI/SHAEIHDI) were synthesized in this article, and their interfacial properties were studied. It was found that SUAEIHDI had a higher CMC value than SHAEIHDI in distillated water at constant temperature (12 ± 2) °C, indicating that it was easier for SHAEIHDI to form micelles in water. The symmetrical molecular structure of SUAEIHDI/SHAEIHDI is composed of lipophilic group and hydrophilic group comprising many active elements i.e. O, N and two imidazoline rings. The novel imidazoline gemini surfactants can be viewed as block-like copolymers, whose surface-modifying effects on nanomaterials are promising. |
