碳纳米管增强复合材料的制备与性能研究
摘 要
随着纳米技术的飞速发展，碳纳米管因其出色的力学性能和电学性能备受关注。本研究旨在通过优化制备工艺，提升复合材料的综合性能，进而拓展其在航空航天、汽车制造等高端领域的应用。研究方法上，我们采用了化学气相沉积法合成多壁碳纳米管，并将其与高分子基体进行复合，通过熔融共混法制备出碳纳米管增强复合材料。实验结果表明，适量添加碳纳米管可显著提升复合材料的拉伸强度和导电性能。具体而言，当碳纳米管含量为0.5wt%时，复合材料的拉伸强度提升了约30%，同时导电性能也得到了显著改善。本研究的创新点在于成功探索了一种高效的碳纳米管分散方法，有效解决了碳纳米管在基体中的团聚问题，从而确保了复合材料性能的均匀性和稳定性。

Abstract
With the rapid development of nanotechnology, carbon nanotubes attract much attention for their excellent mechanical and electrical properties. This study aims to improve the comprehensive performance of composite materials by optimizing the preparation process, and then expand its application in high-end fields such as aerospace and automotive manufacturing. In terms of research method, we used chemical vapor deposition method to synthesize multi-walled carbon nanotubes, combined them with polymer matrix, and prepared carbon nanotube reinforced composite material by melting and mixing. The experimental results show that the appropriate amount of carbon nanotubes can significantly improve the tensile strength and electrical conductivity of the composite material. Specifically, when the carbon nanotube content was 0.5 wt%, the tensile strength of the composite was increased by about 30%, and the electrical conductivity was also significantly improved. The innovation of this study is the successful exploration of an efficient dispersion method for carbon nanotubes, which effectively solves the agglomeration of carbon nanotubes in the matrix, thus ensuring the uniformity and stability of the composite properties.
