Multi-Walled Carbon Nanotubes (MWNTs) -OH Functionalized: Properties, Synthesis, and Applications Introduction Multi-Walled Carbon Nanotubes (MWNTs) are a type of carbon nanotube composed of multiple concentric layers of graphene rolled into cylindrical shapes. Their structure provides superior mechanical, electrical, and thermal properties. Functionalizing MWNTs with hydroxyl (-OH) groups enhances their versatility and compatibility with various materials,...
