英文摘要： This key project aims to develop new, economical and effective strategies for macroscopic-scale elastic conductors with complex and hierarchical architectures. We will focus on the conduction, elasticity and the structure stability of the novel materials. This study will engineer the surface of the conductive nano building blocks to improve their interactions with the three dimensional templates by introducing external fields, such as magnetic field, electric field and gravitational field. The controllable surface functionalization is strongly dependent on the electric charge, hydrophobic property and the choice of surfactants. The relationship between the structure of three dimensional conductors and their properties will be systematically investigated. Moreover, coassembly kinds of nano building blocks with the templates to receive hierarchical structures with improved performance. These macroscopic-scale elastic conductors with interesting property may find applications in optical, magnetic, photoconduction, memory and biosensing devices.
