Pseudopolyrotaxanes or inclusion complexes are supramolecular assemblies formed by a polymer chain, which is threaded by several cyclodextrin (CD) molecules. CDs are cyclic oligosaccharides with a hollow cavity. In this project, we investigate the inclusion complex formation between γ-CD and diblock copolymers containing thermoresponsive poly(N-isopropylacrylamide) (PNIPAAM) chains at silica/liquid interfaces. Ellipsometry, neutron reflectivity and quartz crystal microbalance with dissipation techniques are employed to study the surface properties under different conditions, such as with the presence of CD, at different temperatures and with copolymers of different PNIPAAM block lengths.
