Single wall carbon nanotubes (SWNTs) have attracted considerable interest because of their unique electronic, mechanical and structural characteristics, which provide strong applicability to new functional devices. However, SWNTs are insoluble in water and common organic solvents, thus making them difficult to explore and understand the properties. With the great development of the preparation of SWNTs, it is necessary to bring about the structure functionalization of the basic structure. This paper is mostly concerned on the advances in recent studies on the structure modification of SWNTs, especially highlighting the chemical functionalization and physical adsorption.
