Carbon nanotubes are highly attractive for catalysis due to their extraordinarily high surface area.Carbon nanotubes are hollow tubes made of rolled-up graphene sheets (a single layer of carbon atoms) with diameters typically measured in nanometers and length measuring several microns.For a variety of electrochemical research as well as applications involving chemical and biological sensing, carbon nanotubes are frequently utilized as electrodes.Due to their exceptional mechanical, electronic, thermal, barrier, and chemical properties, carbon nanotube-mediated nanocomposites have gained a lot of attention as promising replacements for more traditional composite materials.Nanotubes are utilized in aerospace and airplanes to reduce the overall load on the system as a whole.CNTs are used to treat breast cancer tumors.Smaller ions in a solution can also be captured using this method. The diameter of the carbon nanotubes can be employed to filter out particles that are too large to pass through.CNTs are attractive as drug delivery and biosensing operating systems due to their unique size, and chemical, optical, electrical, and structural properties, which have made them useful in the treatment of a wide range of diseases.Carbon nanotubes are used in thin-film electronics, actuators, coatings, water filters, automobile components, boat hulls, sporting goods, and electromagnetic shields.CNTs have been employed successfully in pharmacy and healthcare to adsorb or synthesize a variety of therapeutic and diagnostic drugs attributed to their large surface area.Attractive characteristics of carbon nanotubes (CNTs) include their high surface-to-volume ratios, improved conductivity & strength, biocompatibility, simplicity of functionalization, optical features, and more.Some of the remarkable applications are discussed below: They are excellent candidates for a variety of applications due to their superior thermal and electrical conductivity qualities. They can be utilized in a variety of applications, including electronics, textiles including water- and abrasion-resistant fabric, thermal conductivity-based sensors, and many more. Multi-walled Carbon Nanotubes are about 5 to 6 micrometers in length.įigure: Single-walled and multi-walled carbon nanotubes Application of carbon nanotubesīecause of their unique characteristics, carbon nanotubes offer a wide range of possible applications.Multi-walled Carbon Nanotubes have an outer diameter of 2–20 nm and an inner diameter of 1-3 nm, respectively.This particular sort of nanotube has two diameters, the outer diameter, and the inner diameter. Multi-walled nanotubes, also known as MWNTs, are made up of several layers of graphite rolled inward that resemble tubes. have a wide range of applications in the fields of materials science like as electronics, nanotechnology, and optics.They have exceptional strength, and distinct electrical characteristics, and are effective heat conductors.Single-walled carbon nanotubes have a diameter and length of 2 nm and 2 micrometers, respectively.Armchair and zig-zag are a couple of examples of single-walled CNT. Some of the properties are listed below: Single-walled carbon nanotubes abbreviated by SWCNT are seamless cylinders of graphite (also known as graphene) with a diameter of the nanometer range. Types of carbon nanotubes Single-walled Carbon nanotubes They are exceptionally resistant to corrosion as, like graphite, they are highly chemically stable and can withstand almost any chemical reaction unless they are subsequently exposed to high temperatures and oxygen.Regular hexagons make up the crystalline structure of carbon nanotubes.The carbon nanotubes’ density is one-fourth that of steel.Carbon nanotubes have a very high melting point since each carbon atom is strongly covalently bound to three other carbon atoms.They are stronger than steel and as rigid as a diamond.Carbon nanotubes are the stiffest and strongest materials discovered so far on basis of elastic modulus and tensile strength.Carbon nanotubes (CNTs) have high mechanical strength and are both electrically and thermally conductive.They can be as long as a millimeter or even several micrometers. Carbon nanotubes are divided into two categories: single-walled carbon nanotubes (SWCNT), with a diameter of less than 1 nanometer (nm), and multi-walled carbon nanotubes (MWCNT), with diameters up to more than 100 nm and made up of multiple concentrically interconnected nanotubes.
