 seur Gregory Sotzing\, du Département de chimie de l'University of Connec
 ticut.
\nRésumé : Wearable and flexible electronics are being investigat
 ed for systems such as health monitoring\, and displays. Polymeric materia
 ls that conduct electricity may play a role in these future technologies i
 n that they may offer structural variety to meet demanding mechanical requ
 irements as well as the ability to be manufactured in an open air environm
 ent via roll-to-roll procedures. Here\, we will present our research in th
 e area of electrochromics and how we have applied these materials to flexi
 ble\, and stretchable fabrics such as spandex. One key in this development
  was to optimize the electro-chromophore structure such that color selecti
 on would be trivial\, and have this implemented into a single step laminat
 ion procedure. Another key aspect is the development of an organic conduct
 or that has low color and yet high conductivity. As to this\, we have prep
 ared a conductive polymer that suits the need by a chemical reaction at th
 e substrate to conductive polymer interface that induces a phase segregati
 on between the conductive polymer PEDOT (poly-3\,4-ethylenedioxythiophene)
  and its ‘dopant’ or charge compensating polymer\, polystyrene sulfona
 te (PSS). Fabrics achieved by this technique are capable of carrying 250 W
  alternating current with current carrying capacities exceeding 2 Amps/mm2
 . We have also demonstrated that the PEDOT-PSS can be patterned by screen 
 printing\, spay coating\, and by roller stenciling to produce organic cond
 uctive wires on textile with the ability to bend and stretch. The emphasis
  on the chemistry will be structure-property relationships as they pertain
  to color tuning\, as well as presenting PEDOT-PSS as a reactive polymer i
 n which it is both a strong acid and an oxidant.
