In this review, the main approaches were utilized for fabrication nanostructure materials namely arc discharge, laser ablation, chemical vapor deposition, and green synthesis. Also, the advantages and disadvantages for each approach are discussed intensively. In addition, the structure and morphology of Carbon Nanotubes (CNTs), according to the number of layers CNTs classified single-wall carbon tubes (SWCTs), double wall carbon tubes (DWCTs), and multi-wall carbon tubes (MWCTs) are demonstrated in detail. SWCTs can be divided into chiral (m≠n), zigzag (m=0), and armchair (m=n) based on the geometrical arrangement of atoms or molecules. Moreover, some of the mechanical features of CNTs such as Young’s modules, strength and tensile strength, compressibility and deformability and fracture performance will be described. Throughout this review, it can be concluded that CNTs possess better mechanical features comparing with the analogous bulk or micro-scale tubes. For instance, Young’s module of CNTs increases by decreasing radius of CNTs. Furthermore, the strength and tensile strength of CNTs becomes stronger due to this covalent bond between carbon-carbon. On the other hand, compressibility and deformability will also improve due to the anisotropic feature of CNTs shape. It can be concluded that, CNTs possess a wide range of possible uses, and they can be used in nanoscale devices, electronic applications, optical operation, materials science, architecture and many more. Also, CNTs have been utilized in numerous novel applications owing to their unusual electrical features, unique strength, and heat transfer performance.
