摘　　要： 碳纳米管由于其特异的光电及力学性能受到广泛的关注,但其在溶剂中的分散性及与材料的相容性较差,应用受到一定的限制。为了解决这一技术问题,已报道了多种修饰碳纳米管的方法。本文综述了通过自由基反应修饰碳纳米管的各种途径与方法,大体可分为小分子自由基反应改性碳纳米管与大分子自由基聚合反应改性碳纳米管。用于改性碳纳米管的小分子自由基包括芳香偶氮盐、过氧化物分解产生的自由基、卡宾与乃春自由基等;大分子自由基聚合反应包括ATRP、RAFT、NMP、铈离子引发聚合、原位聚合、溶液聚合、沉淀聚合、无皂乳液聚合、乳液聚合等。本文也简要地概述了通过其他途径产生的自由基修饰碳纳米管的方法。 Due to their outstanding electronic, optical and mechanical properties, carbon nanotubes （CNTs） are studied extensively recently, but their poor dispersibility in solvent and bad compatibility with other materials critically limit their application, many approaches and methods for functionalization of CNTs have been reported to solve these problems. All kinds of methods to modification of CNTs with free radical reaction are reviewed in this paper, which include small molecules and macromolecules reaction. Small molecular reaction includes diazonium salts, initiator decompose free radicals, carbene free radicals, and nitrene free radicals. Macromolecules grafting include ATRP, RAFT, NMP, Ce（Ⅳ） ions initiation polymerizaiton, in situ bulk polymerization, solution polymerization, precipitation polymerization, emulsion polymerization, soap-free emulsion polymerization and so on. In this paper, the free radicals generated by other methods to functionalize CNTs are also reviewed briefly.
