摘要:

碳纳米管(CNT)是迄今为止力学性能最高的轻质材料之一,同时兼具优异的导电性和导热性,作为新一代高性能增强材料具有难以估量的发展潜力。特别是以连续碳纳米管纤维和碳纳米管膜为代表与树脂复合制得的连续碳纳米管复合材料,被公认为是具有划时代意义的第3代先进复合材料。本文围绕连续碳纳米管纤维、碳纳米管膜及其与树脂复合形成的复合材料,介绍其制备方法、控制技术、结构特点、力学与功能特性等国内外研究进展,揭示了碳纳米管有序增强体中独特的多级结构特征与多级复合强化机制,阐述了该复合材料应用特色,并展望其应用前景与潜能,以期为碳纳米管纤维复合材料革新未来航空航天超轻结构的多功能化设计与研究提供参考。

Abstract:

Carbon nanotube is considered to be one of the strongest lightweight materials with superior strength and modulus, extraordinary electrical and thermal conductivity. As next-generation reinforcement, carbon nanotube exhibits great potential in polymer composites. Especially, the nanocomposites reinforced by typical carbon nanotube assemblies, carbon nanotube fiber and film, have been recognized as the third-generation advanced composites. This paper reviews recent progress on the continuous carbon nanotube fiber, film and their polymer composites, including their preparation methods, quality control, microstructure, mechanical and physical properties. The multiple-level microstructure of nanocomposite is analyzed and mechanical enhancement mechanism is revealed. The nanocomposite shows great application prospect for electromagnetic interference shielding, fire retardancy, electrical and thermal conductivity, and so on. This review will provide some references for the multi-functional application of carbon nanotube nanocomposites in the future aeronautic and astronautic structures.

Key words: composites, carbon nanotube, carbon nanotube fiber, carbon nanotube film, macroscopic assemblies
