The invention relates to an electrochromic element comprising two substrates having electrically conductive insides, a layered operating electrode which comprises a metal complex compound and which is capable of entering into a redox reaction where the transition from the oxidized to the reduced state is attended by an increase of color depth and the transition from the reduced to the oxidized state is attended by a corresponding weakening of color, an electrolyte layer in the form of a transparent, flexible film, and a counterelectrodewhich is capable of intercalating mobile cations of the electrolyte material and/or of entering into a redox reaction in which when the material of the second electrode changes from the oxidized to the reduced state it exhibits no increase of color depth in the wavelength region of the increase of color depth of the metal complex compound and preferably is not subject to any increase of color depth at all, where the electrolyte layer comprises at least the following components: (a) a crosslinkable hybrid prepolymer, (b) a crosslinkable organic monomer or prepolymer, (c) a non-crosslinkable, thermoplastic organic polymer, and a dissociable salt whose inorganic cations can, in the presence of a charge difference between the operating electrode and the counterelectrode, move between the said electrodes. The electrochromic element is more particularly suitable as constituent of automobile glazing systems.

Electrochromic element with improved electrolyte layer

A flexible transparent electrochromic device, which includes the following components, each of which is a flexible film: a working electrode comprising a transparent conducting substrate supporting an working electrode active material; a counter electrode including a transparent conducting substrate supporting a counter electrode active material; a solid polymer electrolyte (SPE) including a solution of a lithium salt in a polymer solvent. A method for preparing an electrochromic device includes the steps of: preparing a working electrode film, preparing a counter electrode film, preparing a polymer electrolyte film, and assembling the electrodes and the electrolyte, the method being implemented continuously.

Flexible transparent electrochomic device, and a method for the preparation thereof

The present invention relates to a method for the preparation of a novel hybrid electrochromic coating material with superior performance in terms of transparency, electrochromic contrast, coloration efficiency, and adhesion, for a use in electrochromic devices for applications where a high transparency is required in the bleached state.

Highly transparent electrochromic coating material, method for producing the same and use of the material

The present invention is directed to an optically clear coating made from a composition comprising an epoxy-melamine resin. The coating is obtained on a metallic substrate and has a very rigid structure and a unique combination of properties that includes hydrophobicity/easy-to-clean, adhesion to bright chrome, abrasion resistance and chemical resistance. The coating composition comprises (A) a mixture of at least one hydrolysable silane and one hydrolysable metal compound, the compounds of said mixture being partly or fully hydrolyzed and partly or fully condensed, (B) at least one melamine derivative selected from derivatives having formula (CN)(NRR), and derivatives having formula (CN)(NRR)(NRR), wherein Rand Rare independently selected from H, hydroxymethylene and alkoxymethylene, with the proviso that at least one of the Rgroups is a hydroxymethylene or alkoxymethylene group, and Ris &#x2014;CH&#x2014;NR(CN)(NRR)or &#x2014;CH&#x2014;O&#x2014;CHNR(CN)(NRR), and p is 1 or 2, and either at least one partially or fully fluorinated, at least partly hydrolyzed and condensed silane compound, this compound being part of the said mixture (A) of hydrolysable silanes, or (C) at least one partially or fully fluorinated organic compound containing at least one group which may bind to hydroxy groups.
