英文摘要： This key project aims to realize the controllable synthesis of serveral important functional nanowires, their assembly principles and the functionalities of nanowire assemblies. This study will choose one or two nanowires as models to develop their controllable and economize synthesis methodologies and facile assembly techniques on interface. We will focus on how to realize bulky-scale synthesis of high quality nanowires and develop reliable assembly techniques for macroscopic-scale assembly of nanowires. The key issues include the surface functionalization of nanowires and their macroscopic-scale assembly techniques.We will also explore new nanowire assembly systems and reliable assembly techniques based on interface force, capillary force, shear force, field force and so on in order to achieve new assembled structures with new functionalities, and thus develop new pathways for efficiently assembling nanowires and their multicomponent composites. The relationship between the structure of nanowire assemblies and their property will be systematically investigated. New types of ordered nanowire films and their complex hierarchical assemblies with ordering will be discovered,which will be transferred to different substrates including rigid and flexible polymer substrates for device construction. These nanowire asse
