文摘
- •
Diffusion NMR allows to simultaneously study quaternized chitosan and surfactant diffusion coefficients.
- •
Consistent conclusions obtained whatever the used technique (diffusion NMR and conductivity).
- •
Electrostatic nature of interactions can be detected by DOSY experiments.
- •
For concentration ratio of ionic charges larger than 1, surfactant molecules are free and have the same properties than pure surfactant in water solution.
