嵌段共聚物

However, in this paper MesoDyn simulation is used to study interactions between polysaccharide and surfactant. A new and simple approach for studying such a system is found. This study enlarges the application of MesoDyn method in colloid chemistry and provides a new idea for investigating interactions between other type of polymer and surfactant.2. The second novelty of this dissertation is mesoscopic simulation and experiments are combined to study physicochemical properties of system.
