Résumé
Interaction of binary chitosan/nonionic surfactant (NIS) system with sodium dodecyl sulfate (SDS) in aqueous solution is described using turbodimetry, light scattering, electophoretic mobility and cryogenic electron microscopy. The formation of insoluble CHI/SDS complexes is weakened with a decrease in molecular weight of chitosan and critical micelle concentration of NIS as well as with an increase in NIS concentration. Soluble chitosan/NIS complexes absorb SDS molecules until the charge of mixed chitosan/NIS/SDS complexes reaches a critical value that depends on chitosan molecular weight followed by aggregation of primary electrostatic complexes via hydrogen bonding to complex nanoparticles. In contrast to formation of asymmetric swarm-like structures in the binary chitosan/SDS system, the aggregation of complex nanoparticles in the ternary chitosan/NIS/SDS system occurs by a head-to-tail binding mechanism with formation of elongated filamentous microstructures. The finding can be promising for preparation of microbiologically stable pharmaceutical and cosmetic compositions and drug delivery systems containing mixed surfactants.
