CNT Yarn & Tape: Resistance Measurement

A demonstration of the methods & tools we typically use to measure the electrical resistance of our carbon nanotube yarns & tapes.

CNT tape EMI shield: blocking phone reception!

In this video we use a quick and easy experiment to demonstrate that our 5 cm wide carbon nanotube tape is able to effectively block cell phone signals. We have wrapped Tyson’s phone in 2 layers of this tape, which effectively blocks incoming calls due to the tape’s excellent electromagnetic shielding properties.

Carbon Nanotube Tapes up to 5 cm wide!

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 heating elements or conductive materials in clothing or e-textiles.

Making Carbon Nanotube Yarns

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.
