Graphene/rare earth composite aerogel material, preparation method thereof and nuclear reactor thermal insulation material
The graphene/rare earth composite aerogel material provided by the invention has a three-dimensional porous network structure, and pores are filled with a gaseous dispersion medium. The graphene, the rare earth compound and the reinforced fibers are selected as a framework of the graphene/rare earth composite aerogel material, so that the graphene/rare earth composite aerogel material has the advantages of low density, high temperature resistance and low thermal conductivity, and can be used as a nuclear reactor thermal insulation material. In addition, the three-dimensional porous network structure of the graphene/rare earth composite aerogel material can further reduce air convection, so that the composite material has good thermal and mechanical properties under harsh conditions. Furthermore, the graphene/rare earth composite aerogel material provided by the invention is easy to prepare, and continuous industrial production can be realized.
本申请所提供的石墨烯/稀土复合气凝胶材料具有三维多孔网络结构，并在孔隙中充满气态分散介质。通过选用石墨烯、稀土化合物和增强纤维作为石墨烯/稀土复合气凝胶材料的骨架，能够使石墨烯/稀土复合气凝胶材料兼备低密度、耐高温和热导率低的优点，可用作核反应堆隔热材料。此外，石墨烯/稀土复合气凝胶材料的三维多孔网络结构能够进一步降低空气对流，使该复合材料在严苛条件下具有良好的热学以及力学性能。进一步地，本申请提供的石墨烯/稀土复合气凝胶材料易于制备，可实现连续工业生产。
