Abstract
An electrochromic fiber or fabric is disclosed. The fiber or fabric includes a flexible, electrically conductive fiber, and a layer comprising an electrochromic material disposed on and surrounding the flexible, electrically conductive fiber. In one embodiment, the fiber or fabric is both flexible and elastic. The fibers and fabrics are of particular utility in electrochromic devices, particularly those which form or are a part of garments.
Claims17
An electrochromic device, comprising:
- at least two electrodes;
- an electrolyte disposed between the electrodes;
- and
- a potential source in electrical connection with the at least two electrodes,
- wherein at least one of the electrodes comprises one or more of an electrochromic fiber or fabric, comprising:
- a flexible, electrically conductive fiber, and
- a layer comprising an electrochromic material disposed on and surrounding the flexible, electrically conductive fiber.
4 more elements
A method of forming a flexible, electrochromic fiber or fabric, comprising:
- disposing an electrochromic material on a surface of an electrically conductive fiber or fabric to form an electrochromic layer on the surface of the electrically conductive fiber or fabric, wherein disposing the electrochromic material comprises disposing a monomeric electrochromic precursor, and polymerizing the electrochromic precursor to form a polymeric electrochromic layer on the surface of the electrically conductive fiber or fabric;
- and
- disposing the electrolyte comprises disposing a mixture comprising a gel precursor and an electrolyte on the polymeric electrochromic layer, and polymerizing the gel precursor to form the flexible, electrochromic fiber or fabric.
