Amphiphilic copolymers under geometrical confinement
The confinement effects complicate significantly the polymer behavior, however they simultaneously provide opportunities to generate novel nanostructures useful for advanced applications such as nanocontainers or molecular templates. Detailed knowledge of the conformational behavior and self-assembly is necessary also for correct interpretation of separation techniques which employ slow flow of copolymer solutions through microporous media and assume the establishment of thermodynamic equilibria. In our recent studies, inspired by experiments of our collaborators we found that the interaction of copolymers with confining wall modifies the conformational behavior and has an important feedback effect on their sorption and separation.
