Speech Title: Nano-structuring of polymer blends at the interface driven by topology
Abstract: Confining polymers in thin films causes significant deviations of their structural and dynamical properties from their bulk phase behaviour. In our presentation, we show the different effect of the substrate on binary polymer blends with linear and cyclic architecture, as well as miktoarm star polymers in the presence of explicit solvent, by means of extensive molecular dynamics simulations. In the first case, we discuss the role of enthalpic and entropic factors of the interfacial free energy of the system in determining which species in the blend preferentially adsorbs at the substrate [1,2]. In the case of miktoarm polymers, we vary the solvent-block interaction to monitor the effect on the morphology and self-assembly of the polymer film .
