8 more elements
A method comprising the steps of:
- providing a first substrate having a first surface and an opposed second substrate having a first surface opposed to the first surface of the first substrate, the opposed surfaces of the first and second substrates defining a cavity therebetween;
- applying an electrically conductive coating to at least one of the opposed surfaces of the first and second substrates;
- and
- disposing an electrochromic medium in the cavity defined between the opposed surfaces of the first and second substrates;
- wherein the electrochromic medium comprises a solvent comprising:
- at least one low-volatile organic electrolyte solvent based on a cyclic carbonate ester;
- an anodic electroactive material;
- and
- a cathodic electroactive material;
- wherein at least one of the anodic and cathodic electroactive materials is electrochromic;
- and
- wherein the solvent comprises at least one low-volatile organic electrolyte solvent represented by one of the following formulae:
