化学修饰的水溶性碳纳米管

Water-soluble carbon nanotubes prepared by chemical modifications

碳纳米管因其独特的结构和性质受到广泛注意,但它不溶、不熔的特性也限制了它的应用.因此,如何制备可溶解碳纳米管,尤其是在水中可溶解的碳纳米管成为许多领域,特别是与生物医学相关的领域的高度重视,而化学修饰则是获得这一特性的重要手段.从碳纳米管修饰物的化学结构角度出发,综述了不同化合物对碳纳米管的水溶性修饰改性.

Carbon nanotubes（CNTs） attracted many attentions for its special chemical structure and properties.However,the applications of CNTs were severely limited due to its insoluble and infusible characteristics,especially in biomedical field.So the preparation of water-soluble CNTs has become the first step for the potential applications.Because the chemical modification was one of the most efficient methods,the aqueous-soluble modifications applied on CNTs were reviewed according to the chemical structures of modifiers.
