FAILURE CURRENT OF DEXMAT CNT YARN

youtube-video-thumbnail

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 500 microns, a linear mass of 0.18 mg/m, and a linear resistance of 1.3 Ohms/m.

The copper wire is a 36 gauge wire with a diameter of 127 microns, a linear mass of 0.26 mg/m, and a linear resistance of 0.59 Ohms/m.

Note that the voltage measurements shown on the power supply display represent the voltage drop through the entire circuit, not only across the sample being measured.
