EeonTex™—Tunable Electrically-Conductive Fabrics
Take a normal piece of polyester cloth. If you were to test it for electrical conductivity, you’d find the resistance to be somewhere in the neighborhood of 1020 ohms—you’d be better off trying to run current through a soggy, deteriorating stick you found in the woods.
But say we want to make this fabric conductive: until EeonTex™ came along, the only solution was to treat it with a metallic coating, and the only resistance available was .001 ohms—something along the lines of a copper wire.
Now supposing you wanted something between 100,000,000,000,000,000,000 ohms and .001 ohms…
In that vast netherworld lie all manner of inventions and applications waiting to happen. Spotting a 23-order-of-magnitude hole in the market, we developed EeonTex™, a special conductive coating in which individual fibers within a fabric are coated on a nano-scale with inherently-conductive polymers.
Electrical resistance is customizable, based on the thickness of the coating given—we can create patterns and gradients of electrical conductivity as well as patterns or gradients of magnetism. We can even customize other parameters such as porosity and flame resistance!
Other than imparting a slightly darker color, EeonTex™ coatings do not significantly alter the physical characteristics of the textiles. The coatings are stable in sunlight, in high and low humidity, extreme temperatures—you can even throw them in the wash.
Three Types of Coatings
- EeonTex™ PI—lightweight, highly-conductive coatings
- EeonTex™ SD—heavyweight coatings with enhanced stability
- EeonTex™ SL—lightweight coatings with enhanced stability. Suitable for ESD applications, SL coatings come in light colors, and are washable
The Importance of Bridging the Gap
Bridging the conductivity gap paved the way for a number of applications that have already been developed:
- pressure sensing fabric capable of being scanned 500 times/second
- static dissipating clean room suits and bomb suits
- antennas made of fabric
- radar avoidance suits
- “chameleon” body armor that changes colors completely based on temperature
- fabric that allows workers to weld plastic with a microwave
- touch sensitive gloves for precise monitoring of piano students’ fingers
This list is the tip of a very large iceberg, with many, many more applications to come. The possibilities are bounded only by imagination and creativity…
