What are Carbon Nanotubes & Their Properties?

CNT are cylindrical structures of pure carbon with walls just one atom thick. Their diameter is 10,000 times smaller compared to human hair. They were discovered in 1991 and hailed as the Next Revolution in Material Science due to their unique properties including:

Compared to steel

  • 100× higher tensile strength (no fatigue failures)
  • 100× higher thermal conductivity
  • 6× lighter
  • 5× higher modulus

Compared to copper

  • 5× electrical conductivity
  • 15× thermal conductivity
  • 1,000× current capacity

Given their exceptional properties, ideas started pouring in. We would soon be making paper-thin antiballistic vests, flying superlight airframes, and even building a space elevator! The possibilities with CNTs were endless!

It has been 30 years since their discovery. Where is the space elevator?

The Challenge

When manufactured, CNTs clump together into balls of millions, even billions of tubes. These clumps proved to be rather ineffective when added to materials… even detrimental. Attempts to detangle them burned through billions in development dollars. Successes getting the tubes discrete were short-lived as they would re-clump once added to a material.

Many in the scientific, engineering and manufacturing communities began to write off CNTs as a failure and moved on to other pursuits. BUT NOT US!!!

Mechnano Technology

After more than a decade of research and development, Mechnano’s proprietary technology detangles and separates CNTs, then disperses them throughout AM materials without re-clumping.

The resulting discrete tubes (MechT) can be tailored to the specific performance requirements for the selected system and deliver previously unattainable performance.

  • 50% increase in tensile strength
  • 200% increase in toughness
  • 850% increase in tear resistance

Mechnano turns inferior part alternatives into superior solutions—the possibilities are endless and the improvements exponential! Major breakthroughs have led to over 100 issued & pending patents – including composition of matter patents.
