High Purified Hydroxylate Single-walled Carbon Nanotubes (SWCNTs-OH) are widely used in advanced materials and nanotechnology due to their unique properties. They are commonly applied in the development of high-strength composites, where they enhance mechanical, thermal, and electrical properties. In electronics, they serve as conductive fillers in flexible displays, sensors, and transistors. Their hydroxyl functionalization improves dispersibility in aqueous and organic solvents, making them suitable for use in coatings, inks, and thin films. In biomedical applications, they are utilized for drug delivery systems, biosensors, and tissue engineering scaffolds due to their biocompatibility and ability to functionalize with biomolecules. Additionally, they play a role in energy storage devices like supercapacitors and lithium-ion batteries, improving conductivity and charge capacity. Environmental applications include water purification and filtration systems, where they effectively remove contaminants.
