摘　　要：碳纳米管易相互缠结而形成团聚体,因而难于在聚合物中形成良好分散,极大地制约了其在聚合物基复合材料领域的应用。目前,碳纳米管在聚合物中的分散方法主要包括表面化学改性、非共价键包覆改性、机械搅拌、超声分散等。重点概述了碳纳米管表面改性的常用方法,并介绍了相关的应用。Carbon nanotubes are easily intertwisted to form agglomerates so that they are difficult to disperse well in polymer, which significantly restricts their application in polymer-based composites, At present, the dispersion methods ofcarbon nanotubes mainly include surface chemical modification, noncovalent coating modification, mechanical stirring, ultrasonic dispersion, etc. The common methods of surface modification for carbon nanotubes were focused on, and the relevant applications were introduced.
