碳纳米管的表面修饰及其应用

Surface Modification of Carbon Nanotubes and Their Application

摘要: 介绍了碳纳米管的性质和表面修饰方法,综述了近年来国内外有关碳纳米管表面修饰的研究现状,并分析了碳纳米管表面修饰的应用现状.碳纳米管具有独特的管状结构和优异的性能,是制备纳米复合材料的理想增强体之一.因为表面修饰可提高碳纳米管的表面活性、分散能力和与基体材料之间的相容性,从而提高其在复合材料中的增强效果,所以碳纳米管的表面修饰成为碳纳米管研究中的热点之一.

Abstract: Carbon nanotubes (CNTs) are considered as one of the ideal reinforcements for nano-composites due to their peculiar structures and superior properties.Because surface modification of CNTs can improve their surface activity,dispersion ability,and the compatibility between CNTs and base matrix,the surface modification of CNTs are one of hotspot about CNTs investigation.The properties and modified methods of CNTs are introduced,the progresses of the modification of CNTs are reviewed and its application is analyzed.
