Short hydroxy purified multi-walled carbon nanotubes are widely used in the field of materials science for enhancing the mechanical strength and electrical conductivity of composites. They are incorporated into polymers to create lightweight yet durable materials suitable for aerospace, automotive, and sports equipment industries. In electronics, these nanotubes serve as conductive additives in batteries, supercapacitors, and sensors, improving performance and efficiency. Additionally, their high surface area and functional groups make them ideal for use in environmental applications, such as water filtration and pollutant adsorption. In biomedical research, they are explored for drug delivery systems and tissue engineering scaffolds due to their biocompatibility and structural properties.
