In this video, we demonstrate the process that we use for braiding carbon nanotube fibers to make EMI shielding braids or braided CNT yarns. These braids are lightweight and highly flexible. They are also more conductive than stainless steel fiber braids and much stronger than copper wire.

This video demonstrates the array of carbon nanotube tapes that DexMat currently produces. Strong, conductive, and flexible tapes or films up to 5 cm wide are currently available and even wider tape formats are currently under development. These tapes have tremendous potential in applications ranging from EMI shielding in cables/electronics, to thermal interface materials, to […]
This video shows how carbon nanotube (CNT) fibers can be assembled into yarns or ropes by plying the fibers together with a planetary ropemaking machine. These yarns are lightweight and highly flexible. They are also more conductive than stainless steel thread and much stronger than copper wire.
This video highlights the high temperature stability of CNT yarns compared to stainless steel thread by applying a 1430 C butane torch to both materials. The stainless steel thread barely lasts 1 second before melting, while the CNT yarn survives the torch for more than 30 seconds without any visible damage. The high thermal stability […]

Houston, TX- 12/11/2018. Working in collaboration with Minnesota Wire & Cable Company, DexMat has produced carbon nanotube (CNT) tape shielded RG-316 cables that perform comparably to copper (Cu) double braid shielded RG-316 cables. However, the CNT tape shields are 95% lighter than the copper double braid shields. The shielding effectiveness and insertion loss results for the […]
November 28, 2018. Out of the original 17 semi-finalists, DexMat was selected as one of 5 finalists to pitch at the 2018 SpaceCom Entrepreneur Summit in Houston, TX, for the opportunity to win the $100,000 Entrepreneur Challenge. As a runner-up, DexMat won $20,000 in Google Cloud Credits. Click here for more information on the SpaceCom […]
HOUSTON – SpaceCom – The Space Commerce Conference and Exposition, where NASA, aerospace and industry come together to connect, announces the finalists of the SpaceCom Entrepreneur Challenge. Taking place at the George R. Brown Convention Center in Houston November 27-28, this challenge is the culmination of the SpaceCom Entrepreneur Summit (SES). The Entrepreneur Challenge began […]
This video highlights the high temperature stability of CNT yarns compared to copper wire by applying a 1430 C butane torch to both materials. The copper wire lasts about 5 seconds before melting, while the CNT yarn survives the torch for more than 30 seconds without any visible damage. The high thermal stability and superior […]
