英文摘要: For the development of solar thermal conversion technology, this project is to study the absorption properties and its control method of hybrid plasmonic nanofluid. The hybrid plasmonic nanofluid is composed by nanoparticles of different materials, different structures (single-layer common structure, multi-layer composite structure), and different sizes, according to certain principle. The effects of interaction among different nanoparticles on overall absorption will be discussed. And, the synergistic effect of basic characteristics of hybrid plasmonic nanofluid (like particle types, materials, structures, sizes, concentration etc.) on overall absorption properties will be explored. The preparation method of hybrid plasmonic nanofluid will be established, and its photothermal performance will be experimentally tested. Finally, a method to improve photothermal performance of hybrid plasmonic nanofluid will be proposed. This project will enrich the connotation of energy science research and play an important role in improving the utilization efficiency of solar energy. Furthermore, this project will establish the foundation for the development of solar energy utilization technology.
