Patent Images
1. An electrochromic device, comprising:
- a first substantially transparent substrate having an electrically conductive material associated therewith;
a second substrate having an electrically conductive material associated therewith; and
an electrochromic medium contained within a chamber positioned between the first and second substrates which comprises;
at least one solvent;
at least one anodic electroactive material;
at least one cathodic electroactive material;
wherein at least one of the anodic and cathodic electroactive materials is electrochromic; and
a crosslinked polyelectrolyte gel matrix, wherein the crosslinked polyelectrolyte gel matrix increases creep resistance of the electrochromic medium relative to a non-charged gel matrix at the same concentration.
