The research interests and activities of the Polymer Physics Group focus on the study of polymers and amphiphiles both in solution and at interfaces, and interfacial nano-scale systems in general, using a variety of techniques including neutron and x-ray reflectivity, small-angle neutron and x-ray scattering, (SANS, SAXS) atomic force microscopy (AFM), surface force measurements (SF), Fourier-transform infrared spectroscopy (FTIR), surface plasmon resonance (SPR) and electron microscopy (EM). These techniques are employed to investigate the structure and interactions of neutral as well as charged chains, adsorbed or end-tethered to a surface, and in particular polymer brushes formed on free substrates and in confinement. In recent years, the group has conducted extensive studies of the behavior of polymer brushes under strong shear flow regimes both for chains terminally anchored to free surfaces and under geometric confinement. Furthermore, Surface Plasmon Resonance and FTIR methods were developed to study the adsorption kinetics of amphiphiles and block copolymers on solid substrates and in porous materials. Very recently, we have embarked on a study of self-assembled supramolecular structures based on host-guest interactions, using SAXS and SANS. The group continues its development and investigation of nanoporous materials based on the integration of membranes with well-characterised pore structure and stimuli-responsive brushes that offer unique versatility and adaptability to various applications such as tunable size exclusion, controlled release, flow regulation, catalysis, fuel cells, etc.
