Carbon Nanotubes

Unlocking CNT’s potential to make industries lighter, faster, safer, and stronger. 

From lighter planes to stronger buildings, Grokalp helps industries harness CNT's potential for breakthrough innovations.

But what exactly are CNTs doing in the real world? Let's explore 6 mind-blowing applications:

1. Strength and Lightweighting:

  • Think tennis rackets that swing faster, bicycle frames that are lighter yet sturdier, and even aircraft components that soar higher.

2. Electronic Revolution:

  • Get ready for blazing-fast computers and miniaturized electronics with next generation CNT transistors instead of silicon ones. This means faster processing, lower power consumption, and more powerful devices in your pocket.

3. Clean Water for All:

  • Imagine turning seawater into drinking water with ease. CNTs are creating highly efficient membranes for water filtration and desalination.


4. Energy on the Go:

  • Tired of waiting for your EV or phone to charge? CNTs are revolutionizing batteries and supercapacitors, allowing them to store more energy, charge faster, and last longer.

5. Early Cancer Detection:

  • Early detection is key to fighting cancer. CNTs are being used to develop highly sensitive biosensors that can detect diseases like cancer at their earliest stages.

6. Sustainable Hydrogen Power:

  • Hydrogen is a clean and efficient fuel, but producing and storing it can be challenging. CNTs are acting as catalysts for hydrogen production from renewable sources like sunlight and water, and also as efficient storage solutions.

  • Exceptional Properties: Our MWCNTs boast superior strength, conductivity, and versatility, offering unique advantages in various applications.

  • High Purity: 99.9% purity ensures consistent performance and suitability for even the most sensitive applications.

MWCNT Production Comparison: CVD, Arc Discharge & Methane Decomposition


Here's a technical overview and comparison of the three methods you mentioned for producing MWCNTs:

1. Chemical Vapor Deposition (CVD)

  • Technical Overview:

    • Introduces a hydrocarbon gas (like methane) and catalyst (metal nanoparticles) into a heated chamber (700-1000°C).

    • Hydrocarbons decompose on the catalyst, releasing carbon atoms that arrange into MWCNTs.

    • Offers good control over properties like diameter, chirality, and purity.


High energy consumption due to high temperatures.

Requires complex reactor setup and maintenance.


2. Arc Discharge

  • Technical Overview:

    • Creates an electric arc between graphite electrodes in an inert gas atmosphere.

    • Intense heat vaporises carbon, condensing on the negative electrode as MWCNTs.

    • Offers limited control over properties.


Low yield of MWCNTs.

Poor control over properties like diameter and chirality.

Safety concerns due to high voltages and arc.


3. Methane Decomposition (Thermal CVD)

  • Technical Overview:

    • Similar to CVD but focuses solely on methane as the carbon source and high temperatures (above 1000°C) directly decompose it into carbon and hydrogen.

    • MWCNTs form on catalyst surfaces within the reactor.


Simpler setup compared to conventional CVD.

Potentially lower energy consumption than CVD.

These are just a glimpse into the exciting world of CNTs. As research and development continue, expect even more breakthroughs in various fields, shaping a future that is cleaner, healthier, and more technologically advanced.
