    • Carbon Nanofibers

     

    MK Nano provides Carbon Nanofibers manufactured through Chemical Vapor Deposition (CVD) and are of high purity. These are flexible nanofibers having a unique graphitic structure for specialized applications in different sectors due to their superior mechanical, thermal and electrical properties.

    Carbon Nanofibers: Product Details

    The carbon nano fibers (CNFs) manufactured by MK Nano are state-of-the-art nano-materials that have been engineered to offer top performance in specialized applications. These properties make them perfect for sectors dealing with electric equipment, power, and materials:

    • High Strength:

    Strengthens composites to make them last longer.

    • Superior Conductivity:

    Most suitable for high-end electronics and energy storage.

    • Versatile Applications:

    Applicable in catalysis, sensors, and filtration systems.

    • Nanoscale Precision:

    It provides a high surface area, which is important for enhancing the interaction of materials.

    Properties of Carbon Nanofibers

    • High Mechanical Strength:

    It has excellent tensile strength and modulus, which improves how long composite materials last.

    • Excellent Conductivity:

    It can conduct electricity as well as heat better than most materials.

    • Large Surface Area:

    It has a high surface area to volume ratio, making it suitable for catalysis as well as energy storage.

    • Chemical Stability:

    It does not easily decompose or wear away, even when exposed to tough chemicals.

    Preparation Method of Carbon Nanofibers

    With advanced Chemical Vapor Deposition (CVD), MK Nano can guarantee that we have carbon nanofibers of high quality and very pure. It is possible to control the nanostructure by this process.

    • CVD Process:

    Uses transition metal catalysts to break down hydrocarbons at high temperatures.

    • Controlled Growth:

    Maintains consistent nano fiber sizes and characteristics.

    Chemical Vapor Deposition (CVD) Method

    At MK Nano, we use the CVD method for catalytic decomposition of hydrocarbon gases like acetylene, carried out at elevated temperatures of approximately 1100°C with iron catalysts for the production of high-quality carbon nanofibers.

    Frequently Asked Questions About Carbon Nanofibers

    Q: How are carbon nanofibers different from carbon nanotubes?

    A: Carbon nanofibers have larger diameters (50-200 nm) and stacked carbon layer structures, while carbon nanotubes are smaller (1-50 nm) and have tubular, hollow structures.

    Q: Are carbon nanofibers safe for humans?

    A: As long as they are dealt with carefully, carbon nanofibers should not pose any major risks; just like other kinds of nanomaterials, it is important to take appropriate measures so that these particles are not inhaled or their exposure is prolonged.

    Q: What industries use CNFs the most?

    A: The strength and electrical conductivity properties of carbon nanofibers make them essential in various sectors, including electronics, automotive, aerospace, and energy storage.

    Q: What is the size range of a nanofiber?

    A: These nanofibers have diameters ranging from 50-200 nm and lengths that can reach up to 100 µm.

    Q: How strong are carbon nanofibers?

    A: They have high tensile strength, which in most cases is higher than that of normal carbon fibers, hence being ideal for reinforcing composites.

    Q: How big is the nanofiber market?

    A: In 2024, the estimated value of the global market for carbon nanofibers was around USD 5.6 billion and is set to rise significantly in 2025 due to increased demand.

    Q: What is the shape of a nanofiber?

    A: The shape of carbon nanofibers is best described as cylindrical with stacked sp2-bonded carbon layers arranged in cup, plate, or cone configuration, most often.
