Study of complex thermosensitive amphiphilic polyoxazolines and their interaction with ionic surfactants. Are hydrophobic, thermosensitive, and hydrophilic moieties equally important?

Popis výsledku v původním jazyce

The temperature-driven self-assembly of nonionic amphiphilic tailor-made triblock copolymers has been studied by DLS, NMR, ITC, and SAXS. The composition of these triblock copolymers is more complex than that of the vast majority of poly(2-alkyl-2-oxazoline)s: a statistical thermoresponsive (iPrOx) and hydrophobic (BuOx) central block with terminal hydrophilic blocks (MeOx). In general, as temperature increases, nanoparticles form in a process starting with single molecules that become loose aggregatesand ends with the formation of compact nanoparticles. Here, we first attempt to resolve the effects of each block on nanoparticle formation. It has been proven that the iPrOx/MeOx ratio determines the value of the cloud point temperature, whereas the different BuOx?iPrOx blocks determine the character of the process. Finally, we complete our investigation by presenting the thermodynamic and structural profiles of the complexation between these triblock poly(2-alkyl-2-oxazoline)s and two
