摘要

摘要: 碳纳米管(CNTs)具有极高的力学性能、优异的导电和导热性能,被视为理想的复合材料增强相。CNTs增强复合材料已成为一个极为重要的研究领域。然而,由于CNTs与金属基体间相容性、增强体空间分布难以控制、CNTs本身载流量高而电导率相对较低等,CNTs增强金属基复合材料尚未展现出对金属基体电学性能的显著提升,或者无法有效兼顾电学性能和力学性能,整体研究仍处于起步阶段。鉴于此,从预处理、制备方法和电学机制分析等方面概述了CNTs增强金属基复合材料电学性能的研究现状,并展望了该领域的未来发展趋势。

Abstract: Carbon nanotubes(CNTs), due to their extremely high mechanical performance, excellent electrical and thermal properties, have been regarded as ideally reinforcement phase of composites. CNTs reinforced metal matrix composites have become a very important research area. However, due to the issues of the compatibility between CNTs and metal matrix, the difficulty to control dispersion of reinforcement in spatial and the high ampacity but relatively low conductivity of CNTs, the electrical properties of CNTs reinforced metal matrix composites do not show significantly enhancement and the electrical and mechanical properties are difficult to be balanced, the overall research is still in infancy. We discuss the research status of CNTs reinforced metal matrix composites from the aspects of pretreatment, processing method and mechanism of electrical conduction, as well as the outlook for the future development trend in this area.
