- Abstract:
- The micellization on surfaces of two series of quasi-diblock copoly(2-oxazoline)s consisting of
2-phenyl-2-oxazoline (PhOx) segments linked to either 2-methyl-2-oxazoline (MeOx) or
2-ethyl-2-oxazoline (EtOx) segments is investigated in detail. Those micelles are not preexisting
in the initial ethanol solution but are formed during the spin-coating process by the
evaporation of the solvent inducing the precipitation
of the less soluble PhOx segments. The
morphology and size of the surface micelles vary
according to the fraction of PhOx in the copolymers.
Moreover, it is demonstrated that the
chemical nature of the more soluble MeOx or EtOx
segments also has an influence on the morphology
of the resulting surface micelles.
