Industrial Hydroxy Single-walled Carbon Nanotubes (SWNTs-OH) are widely used in various advanced applications due to their unique properties. They are commonly employed in the development of high-performance composites, where they enhance mechanical strength, thermal conductivity, and electrical properties. In the electronics industry, SWNTs-OH are utilized for creating conductive films, transistors, and sensors, offering improved efficiency and miniaturization. Their functionalized surface allows for better dispersion in polymer matrices, making them ideal for coatings and adhesives with superior durability. Additionally, SWNTs-OH play a significant role in energy storage systems, such as lithium-ion batteries and supercapacitors, by improving electrode conductivity and charge capacity. In biomedical fields, they are explored for drug delivery systems and biosensors due to their biocompatibility and ability to functionalize with targeting molecules. Their application in environmental technologies includes water purification and gas sensing, leveraging their high surface area and adsorption capabilities.
