摘要:

碳納米管具有獨特的一維納米結構，優(yōu)異的力學、電學和熱學性能，但在實際應用中由于碳納米管無規(guī)分散且容易團聚，其優(yōu)異的性能很難在材料宏觀層面上充分體現(xiàn)出來。為了促進碳納米管的實際應用，將碳納米管的物理性能從納米尺度拓展到宏觀水平變得越來越迫切。近年來，人們通過濕法紡絲和干法紡絲等過程對碳納米管取向排列，從而制備了具有高拉伸強度和高電導率的纖維，可廣泛應用于線狀太陽能電池和超級電容器等光電轉換和儲能器件中，極大地推動了能源材料和器件的發(fā)展。本文綜述了取向碳納米管纖維的合成方法、結構和性能，重點介紹其作為電極材料在線狀染料敏化太陽能電池和超級電容器等能源領域的應用，最后展望了取向碳納米管纖維的未來發(fā)展方向。

Abstract:

 Carbon nanotubes (CNTs) have been widely studied for characteristic one-dimensional structure, remarkable mechanical, electronic and thermal properties. However, it remains challenging while becomes critically important to extend them to a macroscopic scale due to the aggregation and random dispersion during preparation. Recently, CNTs are highly aligned through wet and dry spinning process to continuously produce CNT fibers that maintain the excellent properties of individual CNTs, and these aligned CNT fibers have been extensively used for wire-shaped solar cells, supercapacitors and other energy devices. This review article will highlight the preparation, structure, property and application of the aligned CNT fibers in recent years with an emphasis on the use in energy, as well as their future direction.
