Abstract
An electrochromic coating is produced by adding an organic moiety to a solution of an electrochromic precursor, said organic moiety having a decomposition temperature greater than, or a vapor pressure sufficiently low at, the temperature at which solution solvent is removed, such that said organic moiety remains integral with the electrochromic precursor coating on said substrate after said solvent evaporates, and said organic moiety having a decomposition temperature lower than, or a vapor pressure sufficiently high at, the temperature at which said electrochromic precursor coating is converted to an electrochromic coating that said moiety is substantially removed from said coating before or during said conversion.
