EeonTexTM Conductive Textiles

EeonTexTM conductive textiles are unique materials made using a proprietary coating technology* developed by a leading textile company. Individual fibers within a fabric or yarn are completely and uniformly coated with doped polypyrrole (PPY), an inherently conducting polymer. Almost all fabrics - woven, knitted, and nonwoven - and textured and spun yarns - synthetic or natural - can be coated using the aqueous process. Typical substrates include polyester, nylon, glass, and Kevlar®. While imparting electrical conductivity and a dark color to the substrates, the coating process barely affects the strength, drape, flexibility, and porosity of the starting substrates. Fabrics are tailor-made for desired resistance, thickness, porosity, surface area, flame-resistance, etc.

Properties

Surface resistivity (per AATCC 76-1987 & ASTM F390-78) controllable to 10% between 10 and 106 ohm/sq

Volume conductivity ranges from 0.0001 to 5 S/cm

Nearly continuous, graduated resistances possible

Thin versions absorb up to 50% of impinging microwave radiation while thicker versions absorb 90% or more

Damps cavity resonances in the GHz region

Polyester twill version dissipates up to 11,600 W/m2

Dissipates static charge instantaneously regardless of humidity

Real dielectric constants range from 2-12 in Ka band

Smooth, mostly resistive, broadband microwave response

Practically insoluble in water and concentrated acids

Easily made into composite laminates, with good resin-to-textile adhesion

Stable in air - degraded by oxidants and alkaline solutions

Encapsulating coatings and matrices that keep out oxygen and ions extend longevity

Health/Safety

The PPY coating is nonmetallic, nontoxic, nonirritating, and nonmutagenic.
