Industrial single-walled carbon nanotubes (SWNTs) are widely used in electronics due to their excellent electrical conductivity and mechanical strength. They are incorporated into transistors, sensors, and conductive films to enhance performance and durability. In the field of energy storage, SWNTs are utilized in lithium-ion batteries and supercapacitors to improve charge capacity and cycling stability. Their high surface area and conductivity make them ideal for these applications. In materials science, SWNTs are added to composites to create lightweight yet strong materials for aerospace, automotive, and construction industries. They enhance tensile strength, thermal stability, and resistance to wear and tear. Additionally, SWNTs are employed in coatings and paints to provide anti-corrosion and conductive properties. In biotechnology and medicine, SWNTs are explored for drug delivery systems, where their unique structure allows for targeted and controlled release of therapeutic agents. They are also used in biosensors for detecting biomolecules with high sensitivity. Overall, SWNTs play a critical role in advancing technology across multiple industries by offering innovative solutions to complex challenges.
