Short High Purified Hydroxylate Single-walled Carbon Nanotubes (SWCNTs-OH) are widely used in various advanced applications due to their unique properties. They are commonly employed as reinforcing agents in composite materials, enhancing mechanical strength, electrical conductivity, and thermal stability. In the field of electronics, they serve as conductive fillers in flexible displays, sensors, and transistors. Their hydroxyl functional groups make them highly dispersible in aqueous solutions, enabling their use in biomedical applications such as drug delivery systems, biosensors, and tissue engineering scaffolds. Additionally, they are utilized in environmental applications for water purification and pollutant adsorption due to their high surface area and reactivity. Their compatibility with polymers and other materials also makes them valuable in energy storage devices like supercapacitors and batteries.
