 Carbon nanotubes, CNTs, have been widely used in a variety of applications due to their unique properties such as high strength and lightweight. However, their low solubility in water and organic solvents has limited their use. To overcome this problem, researchers have developed methods to attach polymers to the surface of CNTs, which can improve their solubility and increase their performance. This review summarizes the different polymer wrapping techniques and their applications, including reinforcing and supporting the unique functionality of CNTs.
