【摘要】：水在建筑学、地质学以及生物学等领域中发挥着重要的作用,而在建筑材料、岩石土壤和生物细胞中又存在着许许多多的纳米级孔,于是纳米孔中冰的熔化行为成为人们研究的重点。在文献所报道中对纳米孔中冰的熔化的研究,我们发现大部分研究是基于Si02为限制系统下进行研究的。Handa等人研究了硅胶介孔材料内冰的熔化、Morishige等人研究了MCM-41介孔材料内冰的熔化、Rault等人研究了SBA-n系列介孔材料内冰的熔化以及Lu.Y等人研究了介孔Si02中冰熔化的尺寸效应等。本论文是通过软模板法制备出不同孔径的有序介孔碳材料FDU-15并对其性能进行测试,为纳米孔中冰的熔化的限制系统的提供新选择。结果表明,成功制备出7种不同孔径的介孔碳材料FDU-15样品,孔径在6.5-4.8nm。并且FDU-15具有良好的机械性能和吸水性,在756MPa下仍然可以保持高度有序的介孔结构；使用论文中的吸水方法可将孔内充满水。所以所制备的FDU-15可以作为研究纳米孔中冰的熔化的限制系统。
[Abstract]:Water plays an important role in architecture, geology and biology, and in building materials, in rock soil and in biological cells, there are many nanoscale holes. Therefore, the melting behavior of ice in nano-pore has become the focus of research. The study of the melting of ice in the nano-pore reported in the literature, We found that most of the research was based on the Si02 system. Handa et al. Studied the melting of ice in silica gel mesoporous materials. Morishige et al. Studied the melting of ice in MCM-41 mesoporous materials. Rault et al. Studied SBA-n series of mesoporous materials. The melting of inner ice and the size effect of ice melting in mesoporous Si02 have been studied by Lu.Y et al. In this paper, ordered mesoporous carbon (FDU-15) with different pore sizes was prepared by soft template method and its properties were tested, which provides a new choice for the melting limiting system of ice in nano-pore. The results show that seven kinds of mesoporous carbon materials FDU-15 samples with different pore sizes have been successfully prepared with pore sizes ranging from 6.5 to 4.8 nm. Moreover, FDU-15 has good mechanical properties and water absorption, it can still maintain a highly ordered mesoporous structure under 756MPa, and the water absorption method in this paper can fill the pore with water. Therefore, the FDU-15 can be used as a limiting system to study the melting of ice in nano-pore.
