受人类鼻孔结构的启发，开发了一种具有鼻孔结构的多功能锂铝硅酸盐/碳纳米管复合材料，用于气体过滤和电磁波吸收。采用催化化学气相沉积(CCVD)法制备了锂铝硅酸盐/碳纳米管复合材料。以具有3D孔结构的锂铝硅酸盐(LAS)陶瓷为骨架，碳纳米管(CNT)原位生长均匀，形成导电网络。与LAS陶瓷相比，碳纳米管的加入显著改善了LAS/CNT复合材料的微波吸收和气体过滤性能。良好的多功能得益于特殊的鼻孔状结构。这项工作不仅在电磁吸波材料领域具有良好的应用前景，而且在气体过滤、催化剂载体等领域也具有很大的潜力。同时也为多功能吸波材料的研究提供了一条新的途径。
Inspired by the nostril structure of human, a multifunctional lithium aluminosilicate/CNT composite with nostril like structure has been developed for gas filtration and electromagnetic wave (EMW) absorption. The lithium aluminosilicate/CNT composites were fabricated by catalytic chemical vapor deposition (CCVD) method. Lithium aluminosilicate (LAS) ceramic with 3D pore structure work as the skeleton, in which carbon nanotubes (CNT) in situ grow evenly and form an electric conductive network. With the addition of CNT, the microwave absorption and gas filtration properties of the LAS/CNT composites have been improved remarkably compared with the LAS ceramic. The excellent multifunction benefits from the special nostril like structure. This work not only has an excellent application prospect in the field of EMW absorbing materials, but also has a great potential in the fields of gas filtration, catalyst carrier and so on. At the same time, it also proposes a new avenue for multifunctional microwave absorbing materials.
