碳纳米管/芳纶纤维复合增强填料的研究进展
|
摘要
首先介绍了碳纳米管的结构和性能,接着指出碳纳米管的优势与缺陷,碳纳米管作为一种新型碳结构的一维纳米材料,具有优异的光学、电学、力学以及导热等性能;但碳纳米管表面缺少活性基团、分散性差、加工困难,限制了其应用。然后介绍了芳纶纤维的种类与性能,引出芳纶纤维对碳纳米管改性的机理,综述了三种芳纶纤维对碳纳米管改性的三种物理方法和一种化学方法,对所得到的新材料的性能也做了一定的分析。最后,展望了纤维与碳纳米管复合材料的发展。
This paper first introduces the structure and properties of carbon nanotubes, and then points out the advantages and disadvantages of carbon nanotubes. Carbon nanotubes, as a novel one-dimensional nanomaterial of carbon structure, have excellent optical, electrical, mechanical and thermal properties. However, the surface of the carbon nanotube lacks active groups, poor dispersion, and is difficult to process, which limits its application. Then the types and properties of aramid fiber are introduced, and the mechanism of modification of carbon nanotubes by aramid fiber is introduced. Three physical methods and a chemical method for modifying carbon nanotubes by aramid fiber are reviewed. The performance of the new materials obtained was also analyzed. Finally, the development of fiber and carbon nanotube composites is prospected.
