Introduction of graphene
Graphene is an example of a carbon nanomaterial in two dimensions. It’s made from carbon atoms as well as SP2 hybrid orbital. It boasts excellent optical and electrical properties and is well-suited for use in many areas such as materials science, nanotechnology, energy and biomedicine. This is a material that will revolutionize medicine in the future. Graphene has been around for a while as a concept. Scientists are well aware that graphite is composed layers of graphene. To describe the structure and properties of carbon nanotubes (graphene), scientists also used curly graphene. Graphene may be a two dimensional structure. But it is actually wavy. These fluctuations are not evident in a system with two layers, but they will disappear in multi-layer orders. Each graphene atom has three connected carbon atoms. A unique single bond allows the electron to freely travel so that graphene conducts electricity. One could say that the entire sheet of graphene forms an bond. The process of making graphene can be done in a few steps. Since we were children, graphene has been prepared. You can easily remove the layer of graphene that you write with with a pencil and form graphene by applying very little force.General intro of carbon nanotubes
Also known as Ba-based tube, carbon nanotubes are one-dimensional, quantum materials. Each cell is sealed at both ends and has a unique radial size of nanometers. Carbon nanotubes are made mainly of hexagonal carbon and atoms. They form many to several concentric tube structures. The average distance between layers is around 0.34nm. While the width is typically 2 – 20nm. You can divide it into three types depending on how the carbon hexagon is oriented along its axial direction. Among them is the helical type, which has chirality. The armchair, zigzag, and spiral CNTs don’t have chirality. Carbon nanotubes do not always appear straight. They are often convex and concave locally, due to the hexagonal pentagonal, and heptagonal formations. To seal the CNT the Pentagon will appear at its top. Heptagonal nanotubes have concave sides. These topological defects could alter CNTs’ helical and electronic bands. It is important to note that the adjacent carbon nanotubes do not bond directly together. However, it does keep some distance.Graphene vs. carbon nanotubes
Graphene stands for the “single layered graphite paper,” and carbon nanotubes refer to the cylinder structures formed by graphene’s curling. The two-dimensional (1D), as well as the one-dimensional (2D), versions of nanomaterials they represent, are complementary in both composition and performance. According to the structure, carbon nanotubes have a one-dimensional crystal arrangement of carbon. While graphene is made up of only one carbon layer, it is a two-dimensional structure. Graphene shares many of the same and better properties as carbon nanotubes. These include high conductivity/thermal conductivity, high carrier mobility; high strength; stiffness; and free-electron movement space. Presently, carbon nanotube research has reached an unprecedented level of depth in terms of preparation technology, performance characterization, and application exploration. There are many similarities between the research methods due to their similarity in composition and structure. The study of carbon nanotubes was a key ingredient in many research methods on graphene. Although graphene has a similar development process to carbon nanotubes (in some ways), it might be quite different. The dispute between two-dimensional or one-dimensional materials is one of the reasons. It is common for nanowires to be at an disadvantage when competing with thin film materials. One carbon nanotube could be considered to be one crystal, with a high aspect rate. However, it is impossible to obtain a carbon nanotube crystal with a high aspect ratio using the present synthesis and assembly techniques. Graphene can be grown in large areas by its two-dimensional crystal structure. Both graphene & carbon nanotubes both have bright futures. I hope that this article has been helpful.
