摘要:	研究期間：10208~10307;“Hierarchical self-assembly” is emerging as an elegant, bottom-up method for fabricating complex nanostructured materials since it allows the concurrent switching of functional properties based on phase transitions of self-assembled structures in response to external stimuli [J. -M. Lehn, Science, 2002, 295, 2400; G. M. Whitesides, B. Grzybowski, Science 2002, 295, 2418]. However, such structural changes in response to external perturbations involve cooperative dynamics at different length levels and different time scales. As a consequent, the conditions of processing govern the final structures and properties of materials. Therefore, understanding the cooperative dynamic and pattern formation of various levels of structures is important for establishing transport mechanisms of hierarchical structures at nonequilibrium conditions in soft materials [Hashimoto, T. Bull. Chem. Soc. Jpn., 2005, 78, 1]. In this research plan, we are interested in the morphology, phase behavior and dynamics of hierarchical self-assembly in BCP thin films since their various complicated morphologies with ordering at different levels offer diverse and versatile benefits as potential nanotechnological applications. The key theme of the proposal is to gain depth understanding the dynamics of the hierarchical self-assembly with phase transitions in response to external stimuli (such as thermal annealing or solvent annealing) in BCP ultrathin and thin films.
