Functionalized Carbon Nanotubes are carbon nanotubes chemically modified with surface functional groups such as –COOH, –OH, –NH₂, and other tailored functionalities. These surface treatments significantly improve dispersibility in polymers, solvents, and biological environments, enabling enhanced interfacial interaction and processing efficiency. Nanographenex functionalized CNTs are well suited for biosensors, targeted drug delivery systems, and nanocomposite reinforcement, supporting reliable performance in both research-driven development and scalable applications.
