Applications Of Multi Walled Carbon Nanotubes (MWCNTs)

Multi-walled carbon nanotubes have great and surprising properties and are widely exploited in a wide range of applications. They are often available in a variety of purity levels and lengths. Multi walled carbon nanotubes have some potential applications, such as additives in polymers, electron field emitters for cathode-ray lighting elements, catalysts, transistors, gas-discharge tubes in telecom networks, batteries, and solar cells.

This guide goes to great lengths about their applications.

  • Medicine

In the field of medicine, a biosensor has been developed that can diagnose yeast infections faster than the present method. The interaction of yeast and antibodies affects the device’s electric current. The antibodies are designed to assault Candida yeast cells, and they are brought into touch with a sample of cells before being connected to a CNT-based transistor. CNTs may also be used to target tumors.

Multi walled carbon nanotubes were injected into mice’s kidneys, and a near-infrared laser was used to target the tumors. CNTs responded by vibrating and killing tumor cells with the heat they produced. MWCNTs are primarily used in solar cells, batteries, nan electronics, transistors, energy storage, and flat panel displays.

  • Batteries

Most portable electronic devices use rechargeable lithium-ion batteries. These batteries discharge a charge when lithium ions pass between two electrodes, one of which is metal oxide and the other graphite. The storage capacity can be increased by replacing graphite with multi walled carbon nanotubes. Carbon nanotube-based electrodes can be ten times lighter and thinner than amorphous carbon electrodes and have a thousand times greater conductivity.

In some cases, such as with electric vehicles, weight reduction can result in a significant reduction in battery power consumption. MWCNTs are employed in supercapacitors, resulting in a power density of 30kW/kg (compared to 4kW/kg for commercially available devices). Supercapacitors can significantly shorten the time required to charge electronics such as cell phones and laptop computers.

  • Solar Cells

Solar cells contain hundreds of micrometer-high towers made of multiwalled carbon nanotubes grown on iron-coated silicon wafers. Each square centimeter of its surface contains 40,000 of these towers. Every tower has millions of multi walled carbon nanotubes that are vertically oriented. As light bounces off the tower’s sides, solar cells collect more light.

Solar cells normally have peak efficiency when the sun is 90 degrees Celsius. In contrast, these cells have two peaks at 45 degrees Celsius and operate with relative efficiency throughout the majority of the day. Because these cells eliminate the requirement for mechanical means of orienting the cells to face the light, they are particularly well-suited to applications in space.

  • Transistors

Transistors constitute the basis of modem integrated circuits, which serve as digital switches. Carbon nanotube variant configurations allow multi walled carbon nanotubes to operate as transistors. Cryogenic temperatures were originally required by switches based on nanotube switches, and the size of individual electrons was predicted.

Bottom Line

Thus, multi walled carbon nanotubes are used in a wide variety of commercial applications because of their excellent properties. MWCNTs (Multi-walled carbon nanotubes) are very strong; they have good capacities for conducting both thermal and electrical energy and, therefore, find a wide number of applications in different ways.

MWNTs have a wide range of present and evolving applications, some of them including composites of improved structure, electrically conductive polymers, battery cathodes, and membranes for water filtration. The key application areas of MWCNTs are Solar cells, Batteries, Nano-electronics, Transistors, Energy storage, and Flat Panel Display.
