In this video we demonstrate the amount of electric current that our 500 micron diameter CNT yarn can sustain in air, and compare this to a copper wire measured with the same apparatus and environment. Here are the precise properties of the materials used in these tests: The CNT yarn has an average diameter of […]
Here we show off the difference between Pi grams of copper wire and Pi grams of our carbon nanotube yarn. Full disclosure: some of the difference in length here is due to the carbon nanotube yarn being thinner. The copper wire in this video is 1.2 mm in diameter; the carbon nanotube yarn ranged from […]
We have talked with many people who are curious about using our carbon nanotube yarn in their projects or products, so we wanted to show off a very simple DIY project of our own. For a limited time this month (March 2019) we are having a sale on our 200 micron diameter carbon nanotube yarn, […]
In this video we provide a brief look at some of the experimental work we are doing to develop new products at DexMat. Here, we are using an electroplating process to coat our carbon nanotube yarn with a layer of copper. This process may allow us to create a useful hybrid material, combining the conductivity […]
A demonstration of the methods & tools we typically use to measure the electrical resistance of our carbon nanotube yarns & tapes.
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.
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 […]
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 […]
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.
