Carbon nanotubes and carbon nanofibers are the same thing? What's the connection?
Carbon nanotubes, as one-dimensional nanomaterials, are lightweight, hexagonal, and perfectly connected with many unusual mechanical, electrical, and chemical properties. In recent years, with the development of carbon nanotubes and nano materials, the broad application prospects of carbon nanotubes and nanomaterials have been emerging. Carbon nanotubes, also known as buckytubes, is a kind of special structure (radial size to the nanometer scale, shaft size of micrometer, both ends of the pipe are basically closed) one-dimensional quantum materials. Carbon nanotubes mainly consist of hexagonal carbon atoms and form coaxial tubes of several layers to tens of layers. The distance between layers is fixed, about 0.34nm, and the diameter is generally 2~20 nm. And according to the different orientations of the carbon hexagon along the axial direction, they can be divided into three types: zigzag, armchair and spiral. Among them, the spiral carbon nanotubes have chirality, while zigzag and armchair carbon nanotubes do not have chirality.
Carbon nanotubes and carbon nanofibers are not the same thing, and they all belong to nanoscale carbon materials.
Carbon nanofibers and nano scale: refers to the length of the larger a certainaspect ratio of linear material, in addition to the diameter, the nano particles filled into ordinary fiber of the fiber is also known as modified nano fiber. In a narrow sense, the diameter of nanofibers is between 1nm and 100nm, but in a broad sense, fibers with a diameter of less than 1000nm are called nanofibers.
