Abstract: The carbon nanotube (CNT) is one of the most important nanotechnology developments. Over the past two decades many researchers around the world have researched CNTs closely because of their huge potential in various fields. CNTs are graphene rolled by hybridization with SP2. The key aspects of CNTs are their lightweight, smaller size with a high aspect ratio, strong tensile strength and good conductive properties, making them useful as fillers in various materials such as polymers, metallic surfaces and ceramics. CNTs haveapplications in the fields of nanotechnology, medicine, transistors, actuators, sensors, membranes and capacitors. There are different techniques that can be used to synthesize CNTs. These include the method of arc-discharge, the chemical vaporizing deposition (CVD), the method of laser ablation and the method of sol gel. CNTs can be multi-walled, doublewalled and single-walled. CNTs have distinct mechanical, electrical, and optical properties which have all been studied extensively. The focus of this analysis is on CNTs synthesis, functionalization, properties, and applications. Often described in a condensed way is the toxic effect of CNTs.
