EeonTex™ Conductive and Piezoresistive Fabrics and Leather

EeonTex™ conductive textiles are unique materials made using proprietary coating technologies.  Individual fibers within a fabric or yarn are completely and uniformly coated with various nonmetallic, conductive formulations. Almost all fabrics – woven, knitted, and nonwoven; synthetic or natural – can be coated using aqueous-based processes. Typical substrate compositions include polyester, nylon, glass, spandex, and aramid. While imparting electrical conductivity and a dark color to the substrates, the thin coatings barely affect the strength, drape, flexibility, stretch, and porosity of the starting substrates. Fabrics are tailor-made for the desired electrical resistance range required by the application, and secondary coatings can be applied to impart environmental protection and flame resistance.

Surface resistivities of EeonTex fabrics range between ~10 and ~10M ohm/sq.  Most of the high resistance fabrics possess suitable piezoresistive character for use as pressure and strain sensors. Thin versions of the fabrics absorb up to 50% of impinging microwave radiation while thicker versions (felts) absorb over 80%. The fabrics provide a mostly resistive, flat, broadband response to radar. EeonTex fabrics can dissipate static charge instantaneously regardless of humidity. They are easily incorporated into composite laminates, usually with good resin-to-textile adhesion. The coatings are nonmetallic, nontoxic, and RoHS compliant.

EeonTex fabrics are used for heating elements, low radar cross section (RCS) structures and gaskets, EMI suppression, artificial horizon/radar barriers, RF curtains, antenna side lobe suppression, impedance matching, biometric pressure mapping sensors, static dissipation, and touch-screen compatible gloves.
