Carbon nanofiber is a term used to describe a material composed of fibers with a diameter of nanometers made entirely of carbon atoms. This material has many synonyms, including carbon nanotubes, carbon fibers, nanocarbon, and nanotubes. Other terms used to describe similar materials include graphene nanofibers, carbonized fibers, and nanocomposites. Carbon nanofibers have unique properties that make them highly desirable for use in many industries, including aerospace, electronics, and energy. They are lightweight, strong, and conductive, which makes them useful for a wide range of applications. The versatility of this material has led to ongoing research into new ways to produce and use carbon nanofibers.
