中文摘要: 具有多层次,多维度,多组分耦合协同效应的分级纳米结构材料在催化,光伏,传感和环境等研究领域有着广泛的应用前景,人们渴望按照自己的想法设计并构筑功能性新型纳米材料,特别是那些具有可控组成,尺寸,形状和形貌的分级纳米结构,为深入设计和研究新型纳米器件提供物质基础。表面修饰在液相合成法制备分级纳米结构过程中往往起到重要作用,由于离子液体功能基团在表面修饰中的优异表现,我们提出这个科学课题,将咪唑基离子液体基团通过特定的手段修饰到聚合物或无机纳米结构表面,利用其离子交换能力和较弱的还原性,研究多组分分级纳米结构的制备工艺,讨论咪唑基粒子液体基团在制备中所扮演的角色,研究其对所生长的另一种纳米结构的形貌、尺寸以及在基底微/纳米结构表面分布状态对构筑的分级纳米结构性能的影响,从而找到构筑多组分分级纳米结构的方法,研制多功能高性能的新型纳米材料。

英文摘要: Hierarchical nanostructured materials with multi-level, multi-dimensional, multi-component coupling and synergy effects have various potential applications in many fields, such as catalysis, photovoltaics, sensors and environment. New functional nanomaterials, especially those with controlled composition, size, shape and morphology of hierarchical nanostructures are eager to be designed and built follow people's own ideas in order to provide the material basis in the area of in-depth design and study of new nanodevices. Surface modification often plays an important role in the process of liquid phase synthesis of hierarchical nanostructures. Due to the outstanding performance of ionic liquid functional groups in the surface modification, we propose this scientific project that imidazole-based ionic liquid groups will be modified by specific means on the surface of polymer or inorganic nanostructurs. Due to make use of ion exchange and the weak reducibility capabilities of midazole-based ionic liquid groups, the preparation methods of multi-component hierarchical nanostructures and the role of imidazole groups in the process will be discussed. The influence of morphology, size and surface distribution of other nanostructures which grow on the surface of micro/nanostructured substrates to the properties of hierarc
