ELECTROCHROMIC WIRE THREAD AND RELATIVE FABRICS

The present invention is directed to eyectrochromic, supercapacitor yarns and the related fabrics. An electrochromic yarn formed by two interwind threads has been invented. The yarn is electrically isolated by a transparent, uncolored polymer. Each thread is the superposition of three concentric layers. The most internal one, the core, has the function of support and/or conductive layer, the second one is the eiectrochromic layer containing conductive nanoparticies, the third layer is a polymer dielectric blend. The yarns described above allows to generate electrochromic fabrics in which the colour can be varied by the application of small electric voltages fed by a battery with variable power supply controlled by a microprocessor connected to a smartphone via Bluetooth technology. A specific application on the smartphone allows to change the voltage supply to the fabrics, in order to get the desired chromatic change.

Modulating fabric diffusivity using tether-containing conducting polymers

An interpenetrating network (IPN) polymer membrane material includes a soft polyurethane interspersed with a crosslinked conducting polymer. The material can be reversibly “switched” between its oxidized and reduced states by the application of a small voltage, ˜1 to 4 volts, thus modulating its diffusivity.
