The discovery of carbon nanotubes (CNTs) by Iijima in 1991 has been a driving force behind global scientific research and technological advancements in the field of nanotechnology. CNTs are cylindrical structures composed of rolled up graphite sheets, with single-wall carbon nanotubes (SWCNTs) consisting of a single layer and multi-wall carbon nanotubes (MWCNTs) consisting of multiple layers. They can range in diameter from fractions of a nanometer to tens of nanometers, with lengths up to several centimeters and typically capped by fullerene-like structures on both ends. CNTs possess fascinating properties that have the potential to revolutionize the material world, particularly in the realm of conductive polymers and CNT-based composites. Researchers have developed various techniques to incorporate CNTs into polymer matrices, aiming to create advanced materials with multifunctional properties. One such aim is to transfer the unique electrical properties of CNTs to otherwise insulating polymer matrices to obtain conducting polymer composites. Different literature reports on CNTs show exceptional mechanical properties. Theoretical and experimental studies indicate that CNTs have an extraordinary elastic modulus exceeding 1 TPa, which is greater than that of diamond (1.2 TPa). Additionally, they exhibit strengths that are reported to be 10 to 100 times higher than the strongest steel, while being only a fraction of the weight. In addition to their mechanical properties, CNTs possess superior thermal and electrical properties. They are thermally stable up to 2800 °C in vacuum, have an electrical conductivity of about 10 3 S cm-1, with an electric current carrying capacity 1000 times higher, and have a thermal conductivity of about 1900 W m -1 K -1 , which is about twice as high as diamond. CNTs possess tremendous potential for use in various scientific and technological fields, particularly as composite fillers in polymers that enhance the resulting composites' mechanical, thermal, and electrical properties. The exceptional strength of CNTs makes them a promising candidate for applications such as biosensors, chemical sensors, batteries, electromagnetic interference shielding, corrosion protection, , solar cells, hydrogen storage, and field-emission materials.
