Multi-Walled Carbon Nanotubes

The Role of Multi-Walled Carbon Nanotubes in Modern Nanotechnology

Nanotechnology is transforming many parts of our lives, from health to electronics. Multi-walled carbon nanotubes (MWCNTs) are at the forefront of this revolution. We at MKnano specialize in giving researchers and innovators like you high-purity, low-cost multiwalled carbon nanotubes. Our products are made to fulfill the high standards of scientific research and industrial use. We can provide you with trustworthy multi-walled CNTs that can meet your exact requirements, whether you need just a few for the lab or bulk volumes for production.

What Are Multi-Walled Carbon Nanotubes?

Multi-walled carbon nanotubes are a form of carbon nanotube that is made up of multiple graphene sheets that are arranged in concentric tubes and fit within each other. At the molecular level, they are like a series of Russian nesting dolls. They are more complex and stronger than single-walled nanotubes, which are made up of a single graphene cylinder.

This layered architecture makes them stronger and more stable at high temperatures, and it also gives them unique electrical characteristics. Making multi-walled carbon nanotubes is also more scalable and cost-effective, which is why they are a popular alternative for many commercial and industrial uses.

MWCNT Properties

  • Physical Properties:

    Multiwalled carbon nanotubes are very strong and light. Because they have a high aspect ratio or length to diameter and a huge surface area, they are great additions for strengthening composite materials.
  • Electrical Conductivity:

    Depending on the structure and chirality of its outermost tube, it may act like a semiconductor or a metal conductor. Because it can be used in so many different ways, it is good for transparent conductive films, sensors, and nanoelectronics.
  • Thermal Conductivity:

    Multi-walled nanotubes are great at conducting heat and capable of dissipating heat efficiently.
  • MWCNT Strength:

    Multi-walled CNTs are one of the strongest materials ever found. They have a tensile strength that is up to 100 times stronger than steel and weigh much less.

Applications of MWCNTs

Multiwalled carbon nanotubes have several excellent characteristics that make them useful for numerous applications, such as:

  • Advanced Composites:

    Making polymers and other materials stronger for use in aircraft, automobile parts, and sports equipment.
  • Electronics:

    Making conductive films for sensors, transistors, and touch displays.
  • Energy Storage:

    Improving the performance and capacity of batteries and supercapacitors.
  • Coatings & Films:

    Making coatings that are conductive and resist static.
  • Biomedical Field:

    Use in medical imaging, medication delivery systems, and biosensors.
  • Water Filtration:

    Making improved membranes for filtering water.
