Properties, Preparation, and Application of Carbon Nanotubes

Abstract

Carbon nanotubes (CNTs), due to their unique one-dimensional nanostructures and extraordinary physicochemical properties, have been a research hotspot in the field of materials science and nanotechnology. Their extremely high strength, good electrical conductivity, and excellent thermal conductivity make CNTs promising for a wide range of applications in many fields. In the medical field, CNTs are used in drug delivery, tumor treatment, and bioimaging due to their excellent biocompatibility and tunable surface properties. Especially in tumor treatment, CNTs can be used as drug carriers to deliver anti-tumor drugs directly to the lesion site and reduce damage to normal tissues. In the energy sector, the application of CNTs is mainly focused on energy storage devices and photovoltaic cells. Their high conductivity and large specific surface area make them ideal electrode materials, especially in supercapacitors and lithium-ion batteries. In addition, CNTs can also improve the photoelectric conversion efficiency of photovoltaic cells and promote the development of renewable energy technologies. In the future, the research of CNTs will continue to deepen, not only to find more efficient and economical applications in existing application fields, but also to explore new application fields, such as applications in environmental monitoring and biosensors. With the continuous progress of preparation technology and the reduction of cost, CNTs are expected to be commercialized in more fields and make greater contributions to the development of human society.
