Graphitized hydroxy multi-walled carbon nanotubes are widely used in advanced materials and technologies due to their unique properties. They are extensively applied in the development of high-performance composites, where they enhance mechanical strength, thermal conductivity, and electrical properties. These nanotubes are also utilized in energy storage systems, such as lithium-ion batteries and supercapacitors, to improve electrode performance and charge-discharge efficiency. In the field of electronics, they serve as conductive fillers in flexible and transparent conductive films. Additionally, their application in catalysis supports efficient chemical reactions due to their high surface area and stability. They are also employed in environmental remediation for adsorbing pollutants and in biomedical applications for drug delivery and imaging due to their biocompatibility and functionalization potential.
