- 3. Introduction Single-walled carbon nanotubes (SWCNTs) are one-dimensional carbon allotropes due to their unique structural, electronic, and mechanical properties have gained significant attention. SWCNTs are composed of a single graphene sheet rolled into a seamless cylinder, which exhibit a range of fascinating characteristics. Here we will discus synthesis methods, characterizations, and applications of SWCNTs
- 4. Synthesis of SWCNTs: • Arc Discharge Method: It is one of the earliest methods known for producing high-quality SWCNTs.in this method creates SWCNTs by vaporizing carbon electrodes in an inert atmosphere. • Chemical Vapor Deposition (CVD): A widely used method for growing SWCNTs on a substrate by catalytic decomposition of hydrocarbons. This method offers better control over diameter and chirality.
- 5. Characterization of SWCNTs • Transmission Electron Microscopy (TEM) TEM is used to visualize the individual SWCNTs and information about their diameter, structure, and defects at the nanoscale. • Raman Spectroscopy: Raman spectroscopy is a non-destructive technique to examine the quality and structural properties of SWCNTs, including chirality and defect density.
