Single walled carbon nanotubes (SWCNTs) are unique materials with many outstanding features. In this simple and easy-to-understand guide, we will discuss their structure, how to spread them evenly, and their special features, such as mechanical, electrical, optical, and thermal properties.

SWCNTs have chemically derived from graphene, an allotrope of carbon. It is a one-dimensional material due to its high aspect ratio. The SWCNT is a one atom thick sheet of graphene that looks like a tube. There are various methods to produce; however, the Catalytic chemical vapor deposition (CCVD) method is one of the popular techniques. We use the same to produce this product. It is one of the popular types of nanotubes, and it possesses a 0 to 2 eV band gap.

At the core, the single-walled carbon nanotubes have sp2 hybrid bonds, and the diameter ranges from 0.7 and 10 nm. Ideally, the diameter is less than or equal to 2 nm. Typically, the product has two configurations - zigzag and armchair.

• Zigzag configuration – It has a graphene-like structure that changes path at a 60-degree angle that alternates in a zigzag pattern on every next step of the bond.
• Armchair configuration – The armchair configuration is similar to the zigzag configuration, the only difference being that the structure changes the path twice. That means there are two turns to the right and left on every four steps, while that of the zigzag was only one.
