复杂表面上高分子薄膜退浸润的模拟研究

The project will carry out large scale computer simulations on the thermodynamics and dynamics of polymer film dewetting on complex surfaces with ordered patterns. We will study the relation between the wetting and dewetting of polymer film and the properties of the polymer itself and the complex surface. We will provide the key factors that determine the dynamical process of the wetting and dewetting, and explain the recent experimental results. The project tries to discover the formation law of the polymer droplets resulted from the dewetting of polymer film, clarify the physics of mechanism to form ordered droplets, and provide theoretical foundation for fabricating polymer films with specific nanostructures. We will also study the influence of nano fillers on the dewetting of polymer film, and search for methods to improve the stability of polymer film by adding nano fillers. The results will be helpful in studying super-cleaning materials and intervention materials, and are also important in the basic theory of soft matter physics as well as in the development of new mattials.
