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.
DexMat at IDTechEx, Santa Clara, 2018
Last month we had the opportunity to show off our carbon nanotube yarns and films at the IdTechEx conference in Santa Clara, CA. In this video, Dmitri describes the various materials and applications that we spoke about at our booth. It was a great show, and we are excited to return to other IdTechEx events […]
DexMat Carbon Nanotube Film: Will it Tear?
The films and yarns manufactured by DexMat are made from well-aligned carbon nanotubes; they are resistant to breaking or tearing across the direction of that alignment. However, when working with these materials it is helpful to keep in mind that their toughness is much lower when the aligned layers are pulled apart. As this video […]
Cutting Carbon Nanotube Yarn
Materials made of aligned carbon nanotubes are very tough, which makes them difficult to cut! This video provides a useful tip for cutting our aligned carbon nanotube yarn to a desired length using a sharp razor. A sharp pair of scissors can also work, so long as the yarn is under tension.

Carbon Nanotube Yarn Tensile Test
A demonstration of a test of ultimate tensile break force performed on a carbon nanotube yarn manufactured by DexMat.
Raw Carbon Nanotubes vs DexMat Material
Here we show the difference between raw carbon nanotubes and the carbon nanotube yarns and films that we make at DexMat.
