碳纳米管基电热材料的结构设计与应用

随着社会的发展，人们的日常生产生活对电热材料提出了更高的要求。碳纳米管因具有轻质、高电导率、高电热转换效率等特点，成为新型轻质高效电热材料的研究热点。纳米尺度的单根碳纳米管无法直接使用，因此，需要以有序的宏观形态进行组装以获得可用的高性能电热材料。介绍了基于碳纳米管的电热材料的主要宏观组装形态，对其结构设计进行了阐述，并对其应用方向进行了介绍，最后对碳纳米管的进一步工业化应用进行了展望。

Structural design and application of carbon nanotube-based electrothermal materials

With the development of society, higher requirements for electric heating materials are proposed by people''s daily production and life. Carbon nanotube has become a research hotspot of novel lightweight and efficient electrothermal materials due to their lightweight, high conductivity, and high electrothermal conversion efficiency. The nano-sized single carbon nanotube cannot be directly used; therefore, it is necessary to assemble it in an ordered macroscopic form to obtain usable high-performance electrothermal materials. The main macroscopic assembly forms of carbon nanotube-based electrothermal materials were introduced, their structural designs were elaborated, and their application directions were introduced. Finally, the further industrial application of carbon nanotube was prospected.
