The general introduction to graphene
Graphene can be described as a two-dimensional form of carbon nanomaterial. It is made up of carbon atoms, SP 2 hybrid orbital and carbon atoms. It is a versatile material with excellent electrical and optical properties. The future is bright for this revolutionary material.
Graphene, as a concept and concept, is not new. Scientists knew for a long time that graphite was made up layers of graphene. To describe carbon nanotubes’ structure, scientists used curly Graphene. Graphene, although it has a 2-dimensional structure, is actually wavy. The fluctuation in graphene is invisible within a two-layer structure, but it disappears completely when there are multiple layers. Each graphene carbon-atom is joined to the three carbon atoms around it by one bond. The rest of graphene’s electrons can be free and move as needed, allowing for electricity conductivity.
You can consider that the entire graphene sheet is a large p-bond. Simple steps are required to make graphene. Since our youth, we have prepared graphene. With a pencil we can peel off the graphene single layer to create graphene.
The general introduction of carbon-nanotubes
One-dimensional quantum materials, such as carbon nanotubes (CNTs), are also known by the name Ba based tubes. Their unique structure (radial dimension is nanometers and axial dimension microns) is what makes them stand out. The cells have both ends sealed. The majority of carbon nanotubes is made up of hexagonal carbon molecules, which create many to dozens concentric tubes. There is a 0.34nm distance between layers and a 220nm diameter. It can be classified into three types based on the various orientations of the carbon hexagon in the axial direction: zigzag (or armchair), and spiral. Among them are helical and armchair CNTs, which have chirality.
Carbon nanotubes can be convex or concave. This is because of the hexagonal formations that are pentagonal and hypertagonal. When the Pentagon is visible at the CNT’s top, it will seal the CNT. When they are hexagonal, the nanotubes become concave. Topological defects may cause changes in the helical structures of CNTs or the electronic band structure close to the faults. The two carbon nanotubes that are adjacent do not bond directly, but they keep some distance.
Graphene vs. carbon nanotubes
Graphene can be described as the “single layer graphite sheet”, which is the main structural unit for graphite. While carbon nanotubes, the cylinder-shaped structure that is formed through the curling and forming of graphene, are carbon nanotubes. These nanomaterials are complementary and perform well in terms of composition and performance. The structure perspective of carbon nanotubes is that they are one-dimensional crystal structures of carbon. The graphene crystal structure is actually two-dimensional, but it only contains one carbon atom layer. Graphene, in terms of physical properties, has many characteristics that carbon nanotubes do not have, including high thermal conductivity and conductivity, high transport mobility, low electron moving spaces, strong strength and high stiffness. Research on carbon nanotubes currently spans a range of disciplines, such as preparation technology, performance characterization, and application exploration. They share many similar research methods because of the close connections between their structure and composition. Many kinds of research were started by related carbon nanotubes studies.
Although the graphene development process is quite similar to those of carbon nanotubes it will likely be different in future. Although there are many factors, it could also be explained by the difference between two-dimensional and single-dimensional materials. The competition for thin-film materials is often a disadvantage to nanowires or nanotubes. As an example, carbon nanotubes can be considered one crystal that has a large aspect ratio. Unfortunately, current assembly and synthesis technology cannot create a macro-sized crystal of carbon nanotubes. This restricts the use of carbon nanotubes. Graphene’s two-dimensional crystal structure is an advantage, which allows for continuous large-area growth. Both graphene, as well carbon nanotubes, have a bright future.
