摘　　要：采用化学修饰的方法制备水分散性碳纳米管(Carbon nanotubes,CNTs)是扩大CNTs在生物传感器、医药、功能材料和电子电器元件等领域应用的重要手段。化学修饰法主要包括非共价修饰和共价修饰两种,非共价修饰是采用表面活性剂、有共轭平面结构的分子以及聚合物或生物大分子对CNTs进行表面包覆;共价修饰包括"grafting to"和"grafting from"两种类型。本文从反应原理和实施方法上综述了化学修饰法制备水分散性CNTs的研究进展,并对水分散性CNTs的研究和应用前景进行了展望。Chemical Modification of water-dispersible Carbon nanotubes（CNTs） is an important way to develop new CNTs materials in bio-sensor, medicals, materials and electrical devices. Chemical modification includes non-covalent and covalent approaches. The former is mainly realized by adsorption of surfactant, conjugate-structured molecules and polymers onto CNTs＇ surface. The latter includes ＇grafting to＇ and ＇grafting from＇ methods. The research and application of the modification mechanism and synthesis process of the water-dispersible CNTs have been reviewed in detail in this paper.
